When the will of God begins to supersede your own will, then you no longer concern yourself with lines.
It’s no longer about “How far can I go without sinning?”.
We all know ourselves and we know what triggers us. If there is a certain behavior, a certain place or a certain activity that triggers sin in your life then AVOID it. The bible says in 1 Corinthians 6:18 to RUN from sexual sin. Not walk casually or speed walk…RUN…as in run for your life, because that is exactly what is on the line. The wages of sin IS death, not MIGHT BE. It will kill you, first spiritually then physically.
Do you want to die today or would rather live for God?
