These lines are for people who accepted Lord Jesus Christ as their savior.
Colossians 2:6-10
6Therefore, as you received Christ Jesus the Lord, so walk in him,
7 rooted and built up in him and established in the faith, just as you were taught, abounding in thanksgiving.
8See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.
9For in him, the whole fullness of deity dwells bodily,
10and you have been filled in him, who is the head of all rule and authority
This teaches us how should we live our lives after receiving a new life in Christ.
All glory to God.
