If you do not have Jesus in their heart, then here is the gospel:
1. God loves and created you to know him personally. He has a wonderful plan for your life.
2. Sin is the problem because of it we cannot know God personally and experience his loving tricks. We try all kinds of things to reach God through transcedental meditation, drugs, alcohol, etc. Even "religion" (I call Christianity a god-made religion not a man-made one). But through this we still cannot know God and have an emptiness still.
3. Jesus made a way, through his holy, blameless life lived on earth, his crucifixion on the cross for our sin (sin means to miss the mark), and his resurrection from the dead. His blood on the cross paid our sin penalty and quenched the wrath of God against us. Through only Jesus can we know God personally and experience his love and plan.
4. We accept this gift by believing in Christ and accepted Him into our hearts as our personal Lord and Savior through prayer.
A prayer like this (this is only an example let the prayer reflect the condition of your heart)
Dear Father in Heaven. I believe in Jesus, as my personal Savior and Sovereign Lord. I accept that he died on the cross for my sins and to cleanse me
from all unrighteousness and that I have been given eternal life and an entry in the Book of Life and that he also resurrected on the third day.
After you have done this, find a local body of Christ or church to go to who read the Bible and believe what it says. Begin a routine of reading the Bible
daily. Praying to God for strength everyday. Also, ask other believers for help in your walk with Christ.
If you are already saved, these are just reminders of what has already occurred in your life. Remember that he is with you and will never leave you or
forsake you. God bless.
