John 5:13 "These things are written... that you may know that you have eternal life."
YOU are a sinner.
Romans 3:23 "For all have sinned and come short of the glory of God"
What will your sin earn you?
Romans 6:23 "For the wages of sin is death (hell) but the gift of God is eternal life through Jesus Christ."
God's gift is eternal life - how did He provide it for you?
Romans 5:8 "But God commendeth His love toward us, in that while we were yet sinners, Christ died for us."
Okay, Christ died for me. How do I appropriate eternal life for myself?
Romans 10:9 "If you confess with your mouth the Lord Jesus and shall believe in your heart that God raised him from the dead, thou shalt be SAVED."
Can I lose my eternal life? No!
John 10:28 "And I give unto them eternal life; and they shall never perish neither shall any man pluck them out of my hand."
