God is love in both substance and expression. The sending of His Son, Jesus (who shares all of His qualities and substance) into our world was the most supreme illustration of love; it cost Him everything but provided for us the only cure for our, otherwise, incurable disease.
God's justice demands that He judges and condemns us at the end of life, because sin is a crime against Him and thus, has eternal consequences. However, because of His love for us, He sent Jesus into our world to save us from inevitable judgment.
The sudden end to Jesus' life was in God's plan all along, because on the Cross God's justice and love for humanity were perfectly satis?ed. In a mysterious transaction, Jesus took upon Himself our sins (our disease and failure) and paid the penalty for them by suffering and dying on the Cross. He bore God's wrath and judgment on our behalf: the death of one perfect man -God's Son, for the lives of many imperfect people - God's creation. Thus, He disarmed, once and for all, the power and effects of sin.
Once His work had finished, Jesus was buried in a tomb. Three days later God brought Him back from the dead to crown His success and present proof of His true identity - that He is, indeed, the Son of God.
The way is now open and clear for us to return to God and begin a new relationship - God and us at peace and adopted into His closest family - forever.
