The doctrine of baptism has faded as a teaching from many that say they follow Christ. The philosophies of men prevail in the religious teachings of our modern era. To be born again as taught in the Bible is to act upon hearing the word of God to repent. Repentance is followed by baptism and the receiving of the gift of the Holy Ghost.
The scriptures are very clear that it is the binding act of faith. When someone comes to realize by witness of the Holy Ghost that they do recognize the ministry and atonement of the Savior as important in their life, something has to change.
That change is symbolized and sealed by an ordinance and covenant. We go down in the water dying as to the old person and coming out washed clean from sin or symbolically resurrected as a new person. We go forward striving to keep the commandments and live a new life patterned after Jesus' example.
This is also the entry into the church and kingdom of God. Those accepting baptism are known and joined in fellowship to nurture their faith. Receiving this gift to repent, manifest by baptism enables the mercy offered by the Saviors atonement to take effect in our lives.
Many say they act in the name of God, but where do they get their authority? They say the Holy Spirit? How can this be confirmed? Anyone can say this. It is not something you get from a book or a college course. The way a person is called to serve is documented in the Bible and no one takes the honor to himself.
God will never fail on his end of the promise to bless us and save us even though we often and regularly fall short. He is willing to constantly forgive us and renew the covenants of salvation as we meet and worship in His church, which is the authorized organization for priesthood government and administration.
