What must I do?
Like Christians, no Muslim would like to be in the darkness. The Bible states that God has sent Jesus to bring people out of darkness into his light (Colossians 1:13; 1 Peter 2:9). He sent Jesus so that through our believing in him, he would grant us assurance, salvation, eternal life and translate us into His heavenly kingdom forevermore. Jesus calls this action “to be born again” (John 3:3-21).
A Jewish ruler once said to Jesus, “Rabbi, we know you are a teacher who has come from God. For no one could perform the miraculous signs you are doing if God were not with Him” (John 3:2). In response Jesus said, “I tell you the truth, no one can see the kingdom of God unless he is born again” (John 3:3) He added by way of further explanation: “no one can enter the kingdom of God unless he is born of water and the Spirit” (John 3:5).
New birth, being born again, is an act of God whereby eternal life is imparted to the person who believes (2 Corinthians 5:17; Titus 3:5; 1 Peter 1:3; 1 John 2:29; 3:9; 4:7; 5:1-4, 18). “Born again” also carries the idea “to become children of God” through trust in the name of Jesus Christ, “to those who believed in his name, he gave the right to become children of God children born not of natural descent, nor of human decision or a husband's will, but born of God” (John 1:12). This fulfills the prophecies concerning God’s Anointed one having spiritual children (Psalm 89:26-33; Isaiah 8:18).
Before His ascension, Jesus gave His disciples the great commission, “Go into all the world and preach the good news to all creation. Whoever believes and is baptized will be saved, but whoever does not believe will be condemned” (Mark 16:15-16).
It was in the light of this command that the apostles of Jesus went out to share the gospel, the good news of assurance available through Jesus. On the day of Pentecost, the apostles of Jesus received the gift of the Holy Spirit. People from all over the world were there that day for this Jewish holiday. They heard Peter’s message about how the prophecies of the prophets were fulfilled in Jesus. They asked the apostles what they should do. Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit” (Acts 2:37-38). The whole of the Book of Acts shows how the message was preached and how both Jews and non-Jews believed in Jesus.
