God loves people and wants to be in a relationship with them. So the ruler and creator of the universe, who is above time and space, became man and lived in history. Jesus Christ is the Son of God, both God and man. He followed his own laws and commands perfectly but was put to death even though he was innocent. Three days later he rose from the dead. He offered his own righteousness and perfect life for all people who are filled with sin and are imperfect.
Isaiah 54:6
"The LORD will call you back as if you were a wife deserted and distressed in spirit"
Romans 4:25
"He was delivered over to death for our sins and was raised to life for our justification."
2 Corinthians 5:21
"God made him who had no sin to be sin for us, so that in him we might become the righteousness of God."
Galatians 4:4
"But when the time had fully come, God sent his Son, born of a woman, born under law, 5 to redeem those under law, that we might receive the full rights of sons."
