When you have come to repent, than you arrived to the second key which Peter got from God, pertaining the baptism in His Name, by which we become cleansed from our sins that we can read in Acts 2:38 (King James version).
Why Baptism by immersion?
The definition of baptism is immersion in water. To get under and to come up out of the water. The Lord was also baptized in water by immersion as example how we need to be baptized, for which He used John the Baptist. This is the only way to speak about baptism.
Why Baptism in the Name of Jesus?
To become cleansed from our sins, it needs to be done in the Name of Jesus, because only by that Name forgiving of sins can be pertained, which you can find in Acts 2:38 where Peter the words spoke, "Repent and be baptized every one of you in the name of Jesus Christ for the remission of sins." This is without any doubt the second key who God had given to Peter
Why has Baptism in the trinity no value?
Because the Lord gives us specific instructions that baptism should be done in His Name and not in titles Father, Son and Ghost. Because in titles the Name of Jesus is not mentioned, in which the Power exist to be saved. Therefore it makes no sense to use titles, because it has no value at all. Only the baptism in the Name of Jesus avails.
Example
When you receive a package from the mailman wherefore you have to sign for receiving, you can not sign with father, son and spirit. But to obtain the package you need to sign with your name. And so it is with the baptism in the Name of Jesus, only than your sins will be forgiven and no way else. Go to the flyer Can I help you?
