Why Baptism?
Repentance
Greek expression: metanoia
Pronunciation: meht AH noy ah
The Greek word for “repentance” is a compound word derived from meta, meaning “after,” and suggesting “some type of change,” and nous, meaning “mind.” Thus, metanoia strictly denotes “a change of mind”—a rejection of past sinful ways. But it also connotes remorse for sin, accompanied by a desire to turn away from one’s sin and to God for salvation. Such repentance accompanies faith in Christ (Acts 20:21).
21 I testified to both Jews and Greeks about repentance toward God and faith in our Lord Jesus.
9 I now rejoice, not because you were grieved, but because your grief led to repentance. For you were grieved as God willed, so that you didn’t experience any loss from us. 10 For godly grief produces a repentance that leads to salvation without regret, but worldly grief produces death.
Repentance, however, is not just a one-time experience. Recognition of daily sins and shortcomings provides the occasion for renewed acts of repentance. A good example of this is found in the book of Revelation in Jesus’ address to the church in Ephesus
1 Be gracious to me, God,
according to your faithful love;
according to your abundant compassion,
blot out my rebellion.
2 Completely wash away my guilt
and cleanse me from my sin.
3 For I am conscious of my rebellion,
and my sin is always before me.
4 Against you—you alone—I have sinned
and done this evil in your sight.
Baptism is an initiatory rite that serves as a proclamation of God’s work in the life of the individual and the Church
19 Go, therefore, and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe everything I have commanded you. And remember, I am with you always, to the end of the age.”
