You must depend on Christ only. Life and strength come from him. You were taught the truth. You must continue to be sure of that true teaching. And always be thankful.
Be sure that no person leads you away with false ideas and words that mean nothing. Those ideas come from people, not Christ. Those ideas are the worthless ideas of people in the world.
In Christ you had a different kind of circumcision. F9 That circumcision was not done by the hands of any person. I mean you were made free from the power of your sinful self. That is the kind of circumcision Christ does.
When you were baptized, F10 {your old self died and} you were buried with Christ. And in that baptism F11 you were raised up with Christ because of your faith in God's power. God's power was shown when he raised Christ from death.
You were spiritually dead because of your sins and because you were not free from the power of your sinful self. But God made you alive with Christ. And God forgave all our sins.
We owed a debt because we broke God's laws. That debt listed all the rules we failed to follow. But God forgave us of that debt. God took away that debt and nailed it to the cross.
God defeated the spiritual rulers and powers. With the cross God won the victory and defeated those rulers and powers. God showed the world that they were powerless.
