Christ’s death and resurrection becomes our death and resurrection. That’s true, first of all, in terms of our relationship with God. God looks on us as we are in Christ—His blood covers our sins, His perfect life covers our inadequacy. Second, it’s true in terms of our experience. God can make us dead to sin—as if we’d been crucified. He can make us alive to the things of the Spirit—as if we’d been resurrected from spiritual death.

The physical act of baptism graphically represents the steps of conversion. First, we’re lowered into the water, we’re immersed completely—just as people who have died are lowered into the grave and covered. This indicates that we have died with Christ and have buried our old lifestyle. Baptism is a funeral, a formal farewell to an existence in which sin dominated. Then, we’re lifted up out of the water by the one baptizing—just like a person being resurrected from the grave. This says that we’re a “new creation,” completely given to the “new life” God has waiting for us.

Only immersion can accurately illustrate the true meaning of baptism—death, burial, and rebirth. “Baptism” by sprinkling doesn’t adequately symbolize the new birth.

What does it really mean to die with Christ?

“For we know that our old self was crucified with him so that the body of sin might be done away with [rendered powerless, margin] that we should no longer be slaves to sin.”
Romans 6:6.

Baptism represents outwardly what a person must do inside: surrender everything to Christ, lay it all out on the table. If we keep anything a secret, if we hold anything back from God, then we’ll likely remain “slaves to sin” in some way. It’s a good idea, as you prepare for baptism, to take a personal inventory and ask God to work in and with you to change anything that He wants you to change. Our transformation will not happen all at once. But we must be willing to put our whole selves in His hands. When we surrender fully to Christ, our sinful desires are “rendered powerless.”

“I have been crucified with Christ and I no longer live, but CHRIST LIVES IN ME. The life I live in the body, I LIVE BY FAITH IN THE SON OF GOD, who loved me and gave himself for me.”
Galatians 2:20.
