that our old man was crucified with Him

Romans 6:6
knowing this, that our old man was crucified with Him, that the body of sin might be done away with, that we should no longer be slaves of sin.

We have heard the expression "crucified with Christ". While we know that our Lord Yshua do not mean for all of us to face the same crucifixion he went through, He does mean for us to crucify ourselves in another way. This way is suppose to be the crucifixion of our own sinful lifes. We have to put that sinful life to death deliberately, to put it on the cross, so that we can have the new transformed life waiting for us. Only in this way can we be free from sin, even in this life.
