Therefore, go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit. – Matthew 28:19
You read in the book of Acts that the disciples baptized the people. They repented from sin, were baptized in water and were filled with the Holy Spirit. In Acts we read that Peter was in the house of Cornelius and while he was preaching to the gentiles ‘the Holy Spirit came on all who heard the message‘ (Acts 10:44). Then Peter said: ‘Surely no one can stand in the way of their being baptized with water. They have received the Holy Spirit just as we have. So he ordered that they be baptized in the name of Jesus Christ.’ (Acts 10:47-48).
We clearly see here that Peter was obedient to the command of Jesus that they should baptize the new believers (so not only sprinkling or pouring water; baptism means to fully immerse into water).
Immediately after the Holy Spirit was poured out on Pentecostal Day and Peter preached under the anointing of the Spirit, they asked the apostles, ‘Brothers, what should we do?’Peter then replied: 1) you must turn back to God, and 2) be baptized in the name of Jesus Christ for the forgiveness of your sins and 3) you will receive the gift of the Holy Spirit (Acts 2:38).
The baptism Peter talked about is the baptism of immersion in water and it is for everyone who is born again and believes in the Lord Jesus Christ. A baby cannot choose yet. The Bible says that children are sanctified by the believing parents. Babies are dedicated and presented to God in churches practicing the adult baptism. Mark 16:16 says: ‘Whoever believes and is baptized will be saved.’Before Jesus began His ministry on earth, He also was baptized (immersed) by John the Baptist. Let us follow Jesus’ example!
