Everybody sins. God knew his creation of beings with free will would sin (1 John 1:8-10). He made provision from the beginning so we could have life forever with him.

For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
John 3:16

Sadly the concept of “sin” is not considered by society as a whole as worthy of the death penalty pronounced by God (Romans 6:21-23.) Each one of us has justified our own sins while condemning others for theirs. The only way to genuine justification is through the atoning sacrifice (the death) of Jesus, the Son of God: “He [Jesus] is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world (1 John 2:2.)”

He prayed for us on his way to execution: “Father, forgive them, for they do not know what they are doing”… (Luke 23:34.)

We are loved because God's nature is to love; we did not earn it; we cannot earn it. “This is how we know what love is: Jesus Christ laid down his life for us... (1 John 3:16.)”
