Redemption
God cannot pretend sin doesn't exist because he is a God of holiness and justice. Because of the seriousness of sin, God sent his beloved, sinless Son to suffer for the redemption of billions of people -- past, present, and future.
Isaiah 53:4-6 Surely He hath born our griefs and carried our sorrows; yet we did esteem Him stricken, smitten of God, and afflicted. But He was wounded for our transgressions; He was bruised for our iniquities; the chastisement of our peace was upon Him, and with His stripes we are healed. All we like sheep have gone astray; we have turned every one to his own way: and The Lord hath laid on Him the iniquity of us all.
Every sinner is invited to humbly receive by faith Christ and his sacrifice on the cross. Just simple, child-like trust.
There is a fountain filled with blood
Drawn from Immanuel's veins
And sinners plunged beneath that flood
Lose all their guilty stain.
