For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. (John 3:16). If that is not plain and simple answer to What Must I Do To Be Saved, here are a few more quotes.
The apostle Paul was asked this same question (Acts 16:30-31) and his answer was “believe in the Lord Jesus Christ and you will be saved.” If you believe that Jesus Christ paid the penalty for your sins, then you are saved!
“And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal,the promised Holy Spirit,” (Ephesians 1:13).
Is there any other way? Good question…”Jesus said to him, I am the way, the truth, and the life: no man comes to the Father, but by me” (John 14:6).
NOTHING ELSE is required.
This is probably the easiest thing to do. We are the ones that make it hard.
