"Let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ. Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?" (Acts 2:36-37).
1) "Repent, and be baptized every one of you in the name of Yahawshua the Messiah (Jesus Christ) for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call" (Acts 2:38-39).
Moreover, get to know Jesus Christ by reading through the Gospels of Matthew, Mark, Luke, and John, and by reading the rest of the New Testament in its entirety. Take note that all power in heaven and in earth has been given unto Christ (Matthew 28:18), and any man who enters in through his door shall be saved (John 10:9). Additionally, consider the following passage:
"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. (John 3:16-18).
