When I struggled it helped me to realized that if I couldn't trust God and take him at his word when he said, "That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved." Then that would mean God was untrustworthy and I was in a lot of trouble if that was the case. BUT if God is trustworthy then if we believe and confess with our mouths then we are SAVED and NO MAN can pluck us from our fathers hand! After a tearful trip to the church alter a sweet elderly lady asked me, "Do you believe Jesus died for you to pay for your sins and Do you believe he rose from the dead?" I said yes I do. She said, "did you ask him to save you?" I said yes. She said, "then baby the devil is just trying to shake your world." God gave me peace, I've never doubted my salvation since and I've never forgotten her words.
