When He did die for us, and was raised again on the third day, He fulfilled once for all the sacrifice of Atonement . He was the one time deal. So His shedding of blood TOOK AWAY the sins of the race of Adam . When someone hears the Word of God, and does not harden their heart to it causes faith to enter. You have now given God, in whom you now believe, the right rule your life.
All faith is the same.
Every born again believer has just as much faith as any other believer. Now you make Jesus the Lord of your life, once you have the faith. I make myself a living sacrifice to you. My life is yours, You bought it with Your blood.
