God is not mocked.
Galatians 6:7, "Do not be deceived, God is not mocked; for whatever a man sows, he will also reap."
Most take this to mean, "You better not mock God by sinning or He'll punish you." But I think "God is not mocked" shares meaning with 2 Corinthians 5:19, "God does not count sins against you." Literally God is not mocked. God is not counting anything you do against you, but you will still receive the consequences of your actions.
It goes on to say in 6:8, "The one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life." Jesus said in John 17:3 that eternal life can be defined as "knowing God" or "relationship with God." So if you sow to the spirit (trust in God, set your mind on the spirit) you will know God more & grow an ever improving relationship with Him.
Avoid Flesh Renovation
"The mind set on the flesh is death, but the mind set on the spirit is life and peace" (Romans 8:6).
The flesh is your physical body & mind. It is what produces sin. Your spirit is "born in the likeness of God" (Ephesians 4:24). It cannot produce sin (1 John 3:9). You don't want to attempt a flesh renovation, not even based on the commands of scripture. Attempting a flesh renovation is "sowing to your flesh." Focusing on the negative qualities & behaviors of yourself or others will cause you to lack peace & reap corruption (an inferior, harmful life). Focus on God & who He has made you in your new born spirit & as Philippians 2:13 says, "God will work in you to desire & to act according to His good pleasure."
