"Anyone who continues to live in Him will not sin. But anyone who keeps on sinning does not know Him or understand who He is."
I like this verse and what it says because I never want to get caught up and use the grace God has given (Jesus on the cross dying and resurrecting) as an excuse to sin. His grace is enough to change our hearts and keep us fixed on Him. We are not slaves to sin, we are righteous because we choose to live in Him. We can't live our lives okaying our sin, that will happen, we must renew our mind daily and say Jesus thank you for your love help me be like you today. As you read more in 1 John I love what it says in verses 7-8, "Dear children, don’t let anyone deceive you about this: When people do what is right, it shows that they are righteous, even as Christ is righteous. But when people keep on sinning, it shows that they belong to the devil, who has been sinning since the beginning. But the Son of God came to destroy the works of the devil."
We might sin because we are not perfect but we don't make a practice of sinning or say "well I am just a sinner saved by grace." We were sinners but our acceptance of Jesus Christ has given us a new birth and we are new creations, righteous just like Him. Verse 9 says, "Those who have been born into God’s family do not make a practice of sinning, because God’s life is in them. So they can’t keep on sinning, because they are children of God." Don't let this world dictate who you are and don't let your new live be about excuses why we still mess up. Believe in the one who died for all of us and freed us from the slavery of sin and this world. Romans chapter 12 verse 2 says, "Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect." It says you will learn to know God's will; you will forget yours. His will is perfect and His will is that we know His Son. We need to open His word everyday and let it transform us so we practice the things that please God not man. Amen
