Jesus paid the Price we were not able to pay

"We despised him and rejected him—a man of sorrows, acquainted with bitterest grief. We turned our backs on him and looked the other way when he went by. He was despised, and we didn't care. Yet it was our grief he bore, our sorrows that weighed him down. And we thought his troubles were a punishment from God, for his own sins! But he was wounded and bruised for our sins. He was beaten that we might have peace; he was lashed—and we were healed! We—every one of us—have strayed away like sheep! We, who left God's paths to follow our own. Yet God laid on him the guilt and sins of every one of us!" (Isaiah 53:3-6, The Living Bible)
Jesus died as my substitute, paying the price for my sins, in my place and opened the way to God, whom I can call Father because Jesus changed places with me.
