Once you are baptized in His Name, you have a new life in Christ. It is through your faith in the working of God, as displayed when He raised Christ from the dead. Entering into this fullness is not something you figure out or achieve. If it’s an initiation ritual you’re after, you’ve already been through it by submitting to baptism. Going under the water was a burial of your old life; coming up out of it was a resurrection,
God raising you from the dead as he did Christ. When you were stuck in your old sin-dead life, you were incapable of responding to God. God brought you alive—right along with Christ! Think of it! All sins forgiven, the slate wiped clean, that old arrest warrant canceled and nailed to Christ’s cross.
