Again this does not mean a person will go through life never committing a sin, know or unknown.
John said that whoever is born of God
cannot sin. (1Jn 3:9) So on some level, in some way, Christians are able to completely abstain from sin.
Sin is not so much as what we do but who we are.
That's true. So if we are going to forsake sin, the change must happen not so much in
what we do, but in
who we are. Can God change that?
We were born to sin...
That
may be true, though it is probably more accurate to say we are born IN sin, rather than TO sin. However, it is certain that we are NOT
re-born TO sin. Sinning does not require re-birth; the natural birth is more than good enough for that.
Instead, we are re-born or re-created in Jesus
for good works. Yes, God does this by grace, through faith, not of ourselves, not by our righteous works. (Eph 2:8-10, Titus 3:5) But His purpose is not for us to continue to sin, but for us to manifest good works, that He may be glorified. (Matthew 5:16)
Perhaps the key is to understand that though we all may be "born to sin" those who are reborn have a completely different purpose. They are no longer who they used to be.
What they do is different because
who they are has been changed. Though they may have been children of wrath by nature, they now partake of the divine nature and are now children of God. (Eph 2:3, 2Peter 1:4, John 1:12) Perhaps more important than what we
were is what we
have become by grace through faith, if indeed we have received Him.
