I was baptized after I was saved as an act of obedience and to show to others that I was now a follower
of Christ. It had nothing to do with me being saved or keeping my salvation--just as works have nothing
to do with being saved or staying saved. We do works not to BE saved but because we ARE saved.
When Jesus said on the cross, "It is finished", He was referring to the finished work of God's plan for our
redemption. He did all that way necessary, and our feeble efforts to help Him save us are at best offensive
to Him. What gall for anyone to think that God needs our help to do anything--including save us or keep us
saved.
If we had a hand in our salvation (other than asking for forgiveness), then we could stand up in heaven
and boast about how we helped the Lord to save us, because His power wasn't enough to do it alone
Such audacity that some people have to believe that they are righteous enough to help procure and to
preserve their salvation when God said, "All our righteousnesses are as filthy rags." They are also calling
God weak, because they obviously believe He is not all-powerful since they think He needs their help.
