The biblical plan of salvation was set forth on the Day of Pentecost by Peter, the dis ciple entrusted with the Keys to the Kingdom of heaven by Jesus Christ. The bible's plan for salvation is repentence from sin, water baptism in the Name of Jesus and receiving the baptism of the Holy Ghost. There must also be a continuance of a Godly life.
Salvation is available to every man, woman, and child on earth.
The decision to accept is up to them. However, you cannot earn salvation by becoming better and better, or by doing good deeds, you must accept the biblical plan. Jesus did the hard part when he died for our sins at Calvary. He left the easy part for us. We are beings of free will and we have the right to use our free will to decide that we want to belong to Jesus Christ.
