The bible says in Romans 10:9 "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." This verse is telling us that all it takes to be saved it believing in Jesus Christ in believing that He died on the cross for our sins and rose up on the third day.
What is being saved? Being saved is being delivered from sin. We have all sinned we have all done something wrong we have all lied we have all stolen but believing in God believing in Jesus delivers us from this. God is giving us a way out a way out of being a slave to sin. This is God's invitation to the world and all it starts with is a belief In Jesus name Amen!
