I noticed your poignant questions in a previous post, Richard, and will here take them up:
You asked, "What does conversion, the new birth, have to do with the desire of this nobleman that his son be healed?" Examining the chapter, it becomes clear in the context of Scripture that this nobleman came to Christ unconverted, and not having experienced the new birth. The Holy Spirit was striving with him, though. The man came to Christ to seek healing for his son--but would not believe in Jesus as the Messiah unless his request was granted. Hence, his faith was not the kind of faith the Bible speaks of in relation to salvation, but a degree of faith as to Jesus' power to heal.
You also asked, "Is the request selfish or unselfish?" This is simple--"The heart is deceitful above all things, and desperately wicked: who can know it?" (Jeremiah 17:9). All we can do apart from Jesus is polluted by sin and selfishness. It can be nothing but that--yet Christ draws upon the selfish heart to long for something greater....and the nobleman was experiencing that striving with His heart by the work of the Holy Spirit.
You then asked, "What is it that causes us to turn to Jesus before we are converted?" Before conversion, we are not fully aware of our sinfulness, and we turn to Christ because "the goodness of God" leads us "to repentance" (Romans 2:4). It is God's leading more than our own power--but the soul submits to this leading, even in its selfish state. That process/experience is the greatest miracle accomplished by divine power (grace): it is the transformation of an enemy of God into a saint. The person whose heart was once selfish and evil receives a new heart through the agency of the Holy Spirit. A new being is begotten in the sight of God. Wondrous love!
Also, you asked, "Is the heart evil or good before the new birth?" This is simple from Scripture, and in the Spirit of Prophecy, many texts are linked together in this powerful paragraph: "By nature the heart is evil, and “who can bring a clean thing out of an unclean? not one.” Job 14:4. No human invention can find a remedy for the sinning soul. “The carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.” “Out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies.” Romans 8:7; Matthew 15:19. The fountain of the heart must be purified before the streams can become pure. He who is trying to reach heaven by his own works in keeping the law is attempting an impossibility. There is no safety for one who has merely a legal religion, a form of godliness. The Christian’s life is not a modification or improvement of the old, but a transformation of nature. There is a death to self and sin, and a new life altogether. This change can be brought about only by the effectual working of the Holy Spirit." {DA 172.1}.
I also appreciated your second, more recent post from today. The statement to which you refer, Richard, is indeed a stark indictment upon the selfish, unrenewed heart. The human heart is so liable to self-deception, and only those who constantly see their need of Jesus, and cling to Him continually, will be kept from the unhallowed effects of self-love and the works of the flesh.
There are many in the church today that are in just such a spiritual condition as was the nobleman. Of them, the Laodicean message is fully applicable:
"And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God; I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth. Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked: I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see. As many as I love, I rebuke and chasten: be zealous therefore, and repent. Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me. To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne." (Revelation 3:14-21).
If Jesus is on the outside of the heart seeking entrance, then He is not abiding in the heart, and the heart is still unregenerate and selfish. But the moment a soul makes a complete surrender and allows Christ entrance, the heart is made new, Jesus transforms the nature, and one becomes a partaker of the divine nature through faith.
Selfishness can so blind a person that they may not even realize the evil of seeking Christ for merely personal, selfish gain. Jesus knows all about this--He turns no self-seeking one away, but seeks to lead us to see our need of His grace to change the heart, so that the very reason for which we came to Him may be cleansed away. Thus, instead our petitions (from the renewed heart) are coming to Him as the expression of grateful love and trust, not of putting God to the test (as was the case of the nobleman in initially seeking Christ, who made conditions of accepting Christ upon the granting of his own request).
Earlier in the chapter, Ellen White makes clear that the nobleman's degree of faith was much akin to others in Israel:
"Yet the nobleman had a degree of faith; for he had come to ask what seemed to him the most precious of all blessings. Jesus had a greater gift to bestow. He desired, not only to heal the child, but to make the officer and his household sharers in the blessings of salvation, and to kindle a light in Capernaum, which was so soon to be the field of His own labors. But the nobleman must realize his need before he would desire the grace of Christ. This courtier represented many of his nation. They were interested in Jesus from selfish motives. They hoped to receive some special benefit through His power, and they staked their faith on the granting of this temporal favor; but they were ignorant as to their spiritual disease, and saw not their need of divine grace."
Reading this statement can remind us clearly of the spiritual condition of many within the Seventh-day Adventist church. Jesus is calling for repentance, for revival, reformation, and true conversion. We can praise the Lord that the very trials that seem to indicate that God has forsaken us can be the very means for allowing a person to see the evil of the unregenerate heart (whether they have their name on the church books is not the issue--the issue is whether one is abiding in Christ and experiencing the new birth each day, for the apostle Paul said, "I die daily" (1 Corinthians 15:31)--the evidence of the new birth is simple--all the fruits of the Spirit are seen in the life, and not one is missing. Like light containing every hue of the spectrum, for "God is light" (1 John 1:5) , it is impossible for the light of His presence to remain hidden if the heart is truly made new by His presence. Hallelujah! The Christian life is an easy yoke so long as we are allied to the power of omnipotence through divine grace!
Clearly, not seeing one's need is itself a lost condition. So we have something very deep going on in this short chapter--the fact that Christ does something to heal the child, but ultimately seeks to lead the nobleman to see His need of a pure heart. It is not enough to have a mere "degree of faith"--but once the soul makes a COMPLETE SURRENDER, it can truly be said that "when we live by faith on the Son of God, the fruits of the Spirit will be seen in our lives; not one will be missing" {DA 676.4}--and that is the experience of the new heart.
Thankfully, the story of the nobleman ends in true conversion:
"The nobleman longed to know more of Christ. As he afterward heard His teaching, he and all his household became disciples. Their affliction was sanctified to the conversion of the entire family. Tidings of the miracle spread; and in Capernaum, where so many of His mighty works were performed, the way was prepared for Christ's personal ministry."
Hence why today we can praise God for the trials He allows--if we are unconverted, it can help lead us to see the evil of our hearts and our need of true conversion; if we are converted, the trials can be the means of allowing Christ to more fully refine us in His image. And if we are converted, but in the trial we fall out of conversion by indulging in murmuring, distrust, fear, repining, or any other of the works of the flesh, we can be brought by the Holy Spirit to conversion again (be re-justified). In confession of our sin and despair of all self-dependence, we are enabled to enter into a deeper repentance, as through the experience we come to realize more fully our need to stay close to Jesus and abide in Him. Look and live!
