Baptism is an outward sign of one's inner need for repentance, connection and relationship with God. It is also, if done correctly, the pathway to be filled with the Holy Spirit. When I say correctly, I mean if your heart isn't in the act, then you've just been submerged in water, but not really baptized. Because to be baptized effectively one has to have an internal desire to follow Jesus as Lord. Most of us at some point have been baptized. When we were young or becoming of age, we were taught that baptism was something you just did to fulfill your religious obligations; so we just did it. But we didn't really own the act; it was not reflective of how we truly felt inside. If this defines your baptism experience, I strongly encourage you to be rebaptized, but this time search your heart and make sure that your reasons and motivations for being baptized center around acknowledging that you have fallen short of God's glorious standard, that you have received the gift of salvation but you want more;  you want to follow Jesus! Additionally we must understand that baptism is an act of submission. When Jesus was baptized, He went to John the Baptist, and though John felt like Jesus should have been baptizing him, Jesus insisted that John had to baptize Him because baptism is an outward sign of one’s inner submission.. The Apostle Paul taught that when we are baptized ,that we are sharing in the death of Jesus. We are crucifying our old selves along with its old lusts and desires. So when you are baptized, you are acknowledging  your need to be one with Christ and your responsibility to come under His authority.
