Biblical explanation
The clearest example is the thief who was crucified beside Jesus. The man acknowledged his guilt, recognized Jesus as the Messiah, and asked Jesus to remember him. Jesus responded with a promise of salvation (). The thief had no realistic opportunity to receive Christian baptism before his death. Another important example is Cornelius. He and his household received the Holy Spirit before Peter baptized them (). Baptism followed God's acceptance of them rather than functioning as a prerequisite that earned that acceptance. Nevertheless, baptism is not optional for a believer simply because salvation is by grace. Jesus commanded baptism (), and the early believers consistently practiced it. The biblical distinction is therefore important: Baptism does not earn salvation, but a person who has accepted Christ should willingly obey Christ's command to be baptized.
In brief
The clearest example is the thief who was crucified beside Jesus.
