In John.8:1-11, a woman who had committed adultery was brought before Jesus by the scribes and Pharisees. By law, she was to be stoned to death. Jesus told the scribes and Pharisees to cast the first stone if they were sinless themselves. No one did and they left the woman alone. Jesus then turned to the woman and said that He too (the most sinless and perfect man) would not cast a stone and condemn her. His last words to her were to 'sin no more'.
You see, before we knew Christ, we were all carnal beings in our sins. When we confessed Him as Lord and saviour, He became the atonement for the remission of all our sins. We were then given the opportunity to start over again; just like the woman whom Jesus saved and forgave.
When Jesus came between us and sin, His atonement was made not for us to continue in sin but so that we would stop doing the things that displeases God and be as perfect before Him. This means we find out what our Lord approves of.
But many who have accepted Christ as Lord, presume they know what is good and right in His eyes. They use their own thinking and logic instead of finding out what God says. There is a way which seems right to man, but that way only leads to death (Proverbs.14:12) Even to presume what is right or wrong is a sin to God (Psalm.19:13). It means you are not turning to Him to guide and lead you; you are turning to yourself, to your own thinking or perhaps someone else’s' opinion instead.
God has an amazing plan for you; one that you are specially made for. When you presume what's right or wrong and how you should take your next steps, you are not allowing Christ to be the author and finisher of your faith (Hebrews.12:2). Stop presuming and start growing your knowledge and understanding by the word so that you can listen better and obey in faith.
Deuteronomy.17:13 And all the people shall hear, and fear, and do no more presumptuously.
Romans.6:1-2 What shall we say then? Shall we continue in sin, that grace may abound? 2 God forbid…
Psalm.19:13 Keep back thy servant also from presumptuous sins; let them not have dominion over me: then shall I be upright, and I shall be innocent from the great transgression.
