You can have everlasting life with God only by your faith in Jesus Christ's crucifixion, resurrection and glorification. You must understand that you and all mankind are totally depraved by nature and unable to please God by your own efforts. God knows your heart, but you can talk to God. Tell Him that you believe and trust in the salvation He has provided for you by His grace. Pray to God from your heart:
Dear God,
I know I have done many sinful deeds. I repent of my sinful ways and turn to You. I know I do not deserve to live forever with You. I know that no one can be justified before You, God, by keeping the Law because no one can be perfect. I believe You came to earth as a man, Jesus Christ, born of a virgin. I believe You took upon Yourself the sins of the entire world - my sins because of Your grace. You were crucified on a cruel cross, and You suffered and died as a substitute for me. You defeated Satan and You defeated death to rise again, and You are now one with the Father. I believe that You, God the Father, Jesus Christ the Son and the Holy Spirit are one God. I thank You God that my Lord and Savior Jesus Christ has removed all my sins. I want to surrender my life to Jesus Christ as my Lord and my God, and follow Him. Please fill me with Your Holy Spirit and fill me with Fire for You, LORD. I believe I will now have eternal life with You. I thank You LORD in the name of Jesus Christ I pray. Amen.
