Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:
1Corinthians 15:1-4
The Apostle then went on to write,
...but there be some that trouble you, and would pervert the gospel of Christ. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
Galatians 1:7-9
To believe in Christ is to believe in who He is, the Savior of mankind, and what He did. Again listen to the Apostle Paul,
But God commended his love toward us, in that, while we were yet sinners, Christ died for us. Much more then, being now justified by his blood, we shall be saved from wrath through him. For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life. And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.
(Romans 5:8-11)
To discover how to be saved just follow this simple plan:
1. Admit to God that you are a sinner. The Bible says, "For all have sinned and come short of the glory of God." (Romans 3:23)
2. Recognize that you are under the penalty of death because of your sin. The Apostle Paul also wrote, "For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord." (Romans 6:23)
3. Know that this death is eternal separation from God in Hell. The Apostle John wrote, "This is the second death. And whosoever was not found written in the book of life was cast into the lake of fire." (Revelation 20:14b-15)
4. Realize that you cannot save yourself. The Apostle Paul writing to the young pastor Titus said, "Not by works of righteousness which we have done, but according to His mercy He saved us, by the washing of regeneration, and renewing of the Holy Ghost; Which He shed on us abundantly through Jesus Christ our Saviour." (Titus 3:5,6)
5. Repent of your sins; have a genuine change of heart toward sin and your God. The Bible says, "For Godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death." (2 Corinthians 7:10)
6. Place your trust in Jesus' death on the cross for your eternal salvation. Again, the Apostle Paul tells us, "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. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation." (Romans 10:9, 10)
