However, the Bible clearly tells us that the Gospel is basically this - the death and resurrection of the Lord Jesus Christ. This is what the early Christians proclaimed and this is the message that Christians should hold central today. So, the Gospel is focused on the Person of the Lord Jesus Christ and the work He has accomplished for each one of us. He is the doorway to all truth and our salvation. Many people have become Christians by simply coming wholeheartedly to Christ in an attitude of humility, faith, and repentance.
Some people find it useful to pray a prayer, similar to the following.
This is just a suggestion based upon the above Scripture references. However, the formula is not important. If you are sincere, and really turn to Christ with all your heart, God will hear your prayer and give freely to you His gift of salvation. Lord Jesus Christ, I believe that you died for my sins and rose again to give me a new life. I am sorry for the wrong things I have done, said, and thought.
