You thought you were the worst person and should not be forgiven and saved, but Jesus died on the cross to forgive all your sins and save you. Such incomparable grace, truly an unconditional love.
1 John 4:9β10 . In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins.
