My dear children, I am writing this to you so that you will not sin. But if anyone does sin, we have an advocate who pleads our case before the Father. He is Jesus Christ, the one who is truly righteous. He himself is the sacrifice that atones for our sins—and not only our sins but the sins of all the world.
1 John 2:1‭-‬2 NLT

So I say, let the Holy Spirit guide your lives. Then you won’t be doing what your sinful nature craves. The sinful nature wants to do evil, which is just the opposite of what the Spirit wants. And the Spirit gives us desires that are the opposite of what the sinful nature desires. These two forces are constantly fighting each other, so you are not free to carry out your good intentions.
Galatians 5:16‭-‬17 NLT

http://bible.com/116/gal.5.16-17.NLT

Therefore I, a prisoner for serving the Lord, beg you to lead a life worthy of your calling, for you have been called by God. Always be humble and gentle. Be patient with each other, making allowance for each other’s faults because of your love. Make every effort to keep yourselves united in the Spirit, binding yourselves together with peace.
Ephesians 4:1‭-‬3 NLT
