WHAT DO YOU THINK? - We have all sinned and deserve God's judgment. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him. Jesus, the creator and eternal Son of God, who lived a sinless life, loves us so much that He died for our sins, taking the punishment that we deserve, was buried, and rose from the dead according to the Bible. If you truly believe and trust this in your heart, receiving Jesus alone as your Savior, declaring, "Jesus is Lord," you will be saved from judgement, and spend eternity with God in heaven.

What is your response?
Yes, today, I'm deciding to follow Jesus

Yes, I'm already the follower of Jesus.
