These ordinances are meaningful rituals to remind us of what Jesus did for us to remind us that He is coming again in the future.
Jesus was baptized by John the Baptist as an example for us to follow. Baptism does nothing to save you. 1 Corinthians 1:17a- “For Christ sent me not to baptize, but to preach the gospel:” According to the Apostle Paul “baptism” was not a part of the saving Gospel. Salvation is through the work of Jesus Christ alone. Baptism occurs after we have been saved, and is simply a picture of Christ’s burial and resurrection. When we are baptized, we are making a public announcement that we want to follow Jesus. We are identifying ourselves publicly as devoted followers of the Lord Jesus Christ.
Being put under the water pictures the burial of Christ in the earth. Coming up out of the water pictures Jesus arising from the grave. Baptism occurs after the new believer understands more about salvation and what it means. After salvation, a believer is to obey Christ and be baptized following Christ’s example. Again, baptism physically does not save you, it just gets you wet. Baptism is an important picture that shows your desire to follow Christ for the rest of your life. Baptism is one of the most important events in a believers life. Even though it has nothing to do with salvation, it has everything to do with setting yourself apart unto God.
