How to become a Christian

 3 simple life giving steps
  1. Each person has done misdeeds (sin) that deserve punishment from a perfect and just God.
  2. However, God being loving, sent his Son, Jesus Christ, to die for our sins on the cross to take the punishment we deserve.
  3. Consequently, when we accept, through faith alone, the forgiveness that Christ provided by his death and resurrection, we receive a permanent relationship with God and eternal life!
 (Ephesians 2:8-9, Romans 10:9-10, and Romans 3:21-26)
