Question: Why did Jesus have to die in order to save man?
Answer: The hardest, most painful and responsible phenomenon in our life is death. The world wasn’t created for dying and for people to bury their dead (Cf. Matthew 8: 22), but for people and other living creatures to live and rejoice. When sin entered this world and the man became mortal, only God was able to correct that mistake and defeat death. The man could not do it because his nature was corrupted by sin. That was why God became incarnate as a man and died for all of us. In fact, God cannot die. The person who obeys God and fulfils his will by enduring suffering till the end will overcome death. That’s why the mystery of our salvation is fulfilled on the Cross. The Cross was the most terrible and deadly tool used for the execution of criminals. So Jesus bore our transgressions and liberated us from the curse of sin. This is why we say, I shall not die, but live, and declare the works of the LORD. (Ps. 118: 17).
St Justin Martyr quoted God as saying, “In whatsoever things I shall take you, in these I shall judge you.” (Dialogue with Trypho, Chapter 47, cf. Matthew 24: 42).
The apostle tells us: "Each of you is a temple of the Holy Spirit." Every human being is a temple. Some temples are built by people and consecrated as houses of the Lord. Other temples of God are not built by hand.
The Lord’s human nature was without sin. He died for us on the Cross. He knew that He had to offer a sacrifice. The Lord took the guilt of the entire humankind because He could do so as our Creator.
Darkness can’t coexist with love and light. Ye cannot serve God and mammon (Cf. Matthew 6: 24). You can’t divide your heart and your life. You’ve got to choose yes or no.
