Yes, we all can sigh and breathe. If we question His power to save us, we should be undone. We know ourselves better than anyone else, except God and Satan. And we know our sinfulness after the Holy Spirit has shown us. We cannot save ourselves and are at the mercy of Christ. He longs to save us. He is continually calling to us, speaking to us, drawing us, revealing His love to us!
The Sabbath Day was given to us that we might know of His creative power. Such power! He spoke and it was!!! And, He has that same power at work to re-create us!!! The promise He makes is that He will finish what He has begun in us! Being confident of this very thing, that He which hath begun a good work in you will perform it until the day of Jesus Christ. Phillipians 1:6. Our part is to feed upon Jesus, to drink His blood and eat His flesh, to behold Jesus! By beholding Him we shall be changed into the same image from glory to glory. (See 1 Cor. 3:18).
