We realize Christian sects have many different ideas regarding baptism. We personally believe that baptism into Jesus includes repentance for sins, remission of sins (the taking away of sins) and the gift of the holy spirit (Acts 2:38).  To us, baptism by water is only the outward manifestation of an internal commitment by the Christian to do God's will in his life. Therefore, baptism is extremely important because it is a visible pledge of a good conscience.  Since water symbolizes the word of God, baptism also pictures a ceremonial washing for a
holy purpose.  Baptism is the immersion into God's word and the study and meditation upon that word cleanses and prepares the Christian for heirship in heaven with our Lord Jesus Christ (Titus 3:5-7). Consequently, if you were baptized as a young child, you probably were not aware of the serious commitment that baptism entails. Once you understand what baptism really means, you may be moved to sacrifice your own will to do the will of God in order to become part of the body of Christ.  If that is the case, you may desire to symbolize that inward commitment by the baptism of water.  Certainly it would definitely not be a sin to be baptized a second time once you fully understand its true meaning.
