While the Church of God celebrates Passover and the Days of Unleavened Bread, the world, including Orthodox Christianity, celebrates Easter — that is, Good Friday, Easter Sunday and, in some countries, Easter Monday. Why do they do it, and why don’t we? Does it make any difference? This sermon will show that it makes a world of a difference. It is so important that we can safely say that it is a matter of life and death. It is a matter of accepting or rejecting Jesus Christ as our personal Savior. It is a matter of receiving forgiveness of sins, or of still living in sin, being cut off from God. If we believe in the Good Friday crucifixion and the Easter Sunday resurrection, we are rejecting the only sign that Christ gave to the people of His time that He was the Messiah — namely, that He would be for three days and three nights dead in the grave, and that He would afterwards raise from the dead.
