Baptism
“Christian baptism is the immersion of a believer in water in the name of the Father, the Son, and the Holy Spirit. It is an act of obedience symbolizing the believer's faith in a crucified, buried, and risen Saviour, the believer's death to sin, the burial of the old life, and the resurrection to walk in newness of life in Christ Jesus. It is a testimony to his faith in the final resurrection of the dead.” Baptist Faith and Message, 2000.
Baptism helps us to follow the command set by Jesus.
18 Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. 19 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, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
Matthew 28:18-20.
It provides a public testimony of your willingness to identify yourself as a follower of Jesus.
8 For it is by grace you have been saved, through faith--and this not from yourselves, it is the gift of God--9 not by works, so that no one can boast. 10 For we are God's workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do.
Ephesians 2:8-10
Communion or “The Lord’s Supper”
The Lord's Supper is a symbolic act of obedience whereby members of the church, through partaking of the bread and the fruit of the vine, memorialize the death of the Redeemer and anticipate His second coming. Baptist Faith and Message, 2000.
Communion is a simple act designed to help us remember the power of Jesus’ death and His awaited Second Coming
17 In the following directives I have no praise for you, for your meetings do more harm than good. 18 In the first place, I hear that when you come together as a church, there are divisions among you, and to some extent I believe it. 19 No doubt there have to be differences among you to show which of you have God's approval. 20 When you come together, it is not the Lord's Supper you eat, 21 for as you eat, each of you goes ahead without waiting for anybody else. One remains hungry, another gets drunk. 22 Don't you have homes to eat and drink in? Or do you despise the church of God and humiliate those who have nothing? What shall I say to you? Shall I praise you for this? Certainly not! 23 For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, 24 and when he had given thanks, he broke it and said, "This is my body, which is for you; do this in remembrance of me." 25 In the same way, after supper he took the cup, saying, "This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me." 26 For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes. 27 Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. 28 A man ought to examine himself before he eats of the bread and drinks of the cup. 29 For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself.
