"And it shall come to pass that whoever calls on the name of the Lord shall be saved..." - Joel 2 V32

"that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved." - Romans 10 V9

Considering man's helplessness, God Himself provided the sacrifice for the sin of mankind and He offered the free gift of salvation to anyone who would believe on the Lord Jesus. Whoever calls on the name of the Lord Jesus shall be saved. Praise God!
