Salvation and Conditional Statements in the Bible
Besides the ‘if’ statements in the Bible, there are verses that set conditions regarding salvation.
21 After they had preached the gospel to that city and had made many disciples, they returned to Lystra and to Iconium and to Antioch,
22 strengthening the souls of the disciples, encouraging them to continue in the faith, and saying, "Through many tribulations we must enter the kingdom of God."
If the disciples were being encouraged to continue in the faith, there must have been some chance of them not continuing in the faith-thus they could walk away from the faith. If they were disciples, they were born again.
