36 “Therefore let all the house of Israel know assuredly that God has made this Jesus, whom you crucified, both Lord and Christ.” 37 Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, “Men and brethren, what shall we do?” (Acts 2:36–37, NKJV)
When convicted that Jesus is Lord and Christ, sinners were cut to the heart for their sins against Him. Their urgent question was, “What shall we do?” The answer Peter gave was clear: Repent and be baptized (Acts 2:38). Today, people give different answers to the same question. Some say, “You can’t do anything – God must do everything for you to be saved.” That is not what Peter said. Some say, “Believe and pray the sinner’s prayer, and you will be saved.” That is not what Peter said. Some say, “God has already elected who will be saved and who will be lost, so whatever you do will not change your fate.” That is not what Peter said. Some say, “Plead for Holy Spirit baptism in addition to being baptized in water so you can be fully sanctified.” That is not what Peter said. Why not just do what Peter said? About three thousand believers were saved that day when they repented and were baptized (Acts 2:40-41). The way to be saved by Christ has not changed. The need for salvation is the same. The answer to the question, “What shall we do?” is the same. This is gospel salvation. Believe it. Obey it. Be saved by Christ.
