“ So then, just as you received Christ Jesus as Lord, continue to live in Him, rooted and built up in him, strengthened in the faith as you were taught, and overflowing with thankfulness.”

 

Colossians 2:6-7
 

 

How can you behave in a way God wants you to? And know you are?
 

I would say that the most important thing is to go by what God's Word says. God will never ask you to do something that is not in keeping with what his word says. We do lots of things that are not in keeping with God's Word - in fact sometimes are against His Word. And when we do that - We know it. This is called sin. Our heart , where God's Spirit works will soon convict us and rebuke us.
And likewise when we behave - using God's Word as our rule for life, we will experience His peace in our heart. The truth testifies to itself. When you hear the truth - you know it's right - and when you live the truth, you know deep down it's right. When we live in a right way, we please God, and enjoy that sense of being right with God. a Christian who has the channels open with God will instinctively know whether something is right or wrong. But the Word is always our guide.
