Why was it necessary for Christ, the redeemer, to die?

Christ died willingly in our place to deliver us from the power and penalty of sin and bring us back to God.

Crucified Between Two Criminals

32 As they were going out, they found a Cyrenian man named Simon. They forced him to carry his cross. 33 When they came to a place called Golgotha (which means Place of the Skull), 34 they gave him wine mixed with gall to drink. But when he tasted it, he refused to drink it. 35 After crucifying him, they divided his clothes by casting lots. 36 Then they sat down and were guarding him there. 37 Above his head they put up the charge against him in writing: This Is Jesus, the King of the Jews.

38 Then two criminals were crucified with him, one on the right and one on the left. 39 Those who passed by were yelling insults at him, shaking their heads 40 and saying, “You who would destroy the temple and rebuild it in three days, save yourself! If you are the Son of God, come down from the cross!” 41 In the same way the chief priests, with the scribes and elders, mocked him and said, 42 “He saved others, but he cannot save himself! He is the King of Israel! Let him come down now from the cross, and we will believe in him. 43 He trusts in God; let God rescue him now—if he takes pleasure in him! For he said, ‘I am the Son of God.’” 44 In the same way even the criminals who were crucified with him taunted him.
The Death of Jesus

45 From noon until three in the afternoon, darkness came over the whole land. 46 About three in the afternoon Jesus cried out with a loud voice, “Elí, Elí, lemá sabachtháni?” that is, “My God, my God, why have you abandoned me?”

47 When some of those standing there heard this, they said, “He’s calling for Elijah.”

48 Immediately one of them ran and got a sponge, filled it with sour wine, put it on a stick, and offered him a drink. 49 But the rest said, “Let’s see if Elijah comes to save him.”

50 But Jesus cried out again with a loud voice and gave up his spirit. —Matthew 27:32-50

Sin is Condemned

For I passed on to you as most important what I also received: that Christ died for our sins according to the Scriptures, —1 Corinthians 15:3

For freedom, Christ set us free. Stand firm, then, and don’t submit again to a yoke of slavery. —Galatians 5:1

Love is Presented

4 But God, who is rich in mercy, because of his great love that he had for us, 5 made us alive with Christ even though we were dead in trespasses. You are saved by grace! —Ephesians 2:4 -5

An Example is Set

6 who, existing in the form of God,
did not consider equality with God
as something to be exploited.
7 Instead he emptied himself
by assuming the form of a servant,
taking on the likeness of humanity.
And when he had come as a man,
8 he humbled himself by becoming obedient
to the point of death—
even to death on a cross. —Philippians 2:6-8
