The Bible says that I cannot sin. Here's some Scripture on that...
Romans 6
How shall we, that are dead to sin, live any longer therein?
our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
For he that is dead is freed from sin.
he died unto sin once: but in that he liveth, he liveth unto God.
Likewise reckon ye also yourselves to be dead indeed unto sin,
For sin shall not have dominion over you: for ye are not under the law,
Being then made free from sin, ye became the servants of righteousness.
being made free from sin, and become servants to God,
1 John 3 & 5
Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
Whosoever is born of God doth not commit sin, for his seed remaineth in him: and he cannot sin, because he is born of God.
We know that whosoever is born of God sinneth not.
