Again, I agree 100 percent with jp87. Simply dipping you in water doesn’t make you be born again. You do have to ask Jesus to have you born again.
So, how do you ask Jesus to have you born again? The Bible tells us, and gives definite directions on the way Jesus wants us to ask him. Not just any old way, but Jesus’ way. This way is described in 1 Peter 3:20,21, “…eight persons were saved through water. Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a clear conscience.”
When you are dipped into the waters of Baptism, you are not doing it to wash dirt off. Ordinarily when you bathe, you do it to wash dirt off, because water by its nature has that power.
In baptism, however, you do it to wash your conscience. Scripture explicitly states that baptism is itself the appeal, the prayer to God, to have your conscience washed.
So, baptism is the way Jesus wants you to ask Him to have you born from above.
And how do you know your prayer, your appeal, will be answered? Peter goes on to say, “…through the resurrection of Jesus Christ, who has gone into heaven and is at the right hand of God, with angels, authorities, and powers subject to him.” Jesus’ resurrection proves he can and will give the waters of baptism the power to clean your conscience, and you will be born from above. (Of course, when you are born from above, you are also born again!)
And it is true, when you are born again, you are a different person. Not only that, but a new person, a new creature.
