First Corinthians chapter one and verse twenty-three says, But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness; But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God.
The Bible says in Genesis chapter four, And Abel was a keeper of sheep, but Cain was a tiller of the ground. And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD. And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering: But unto Cain and to his offering, he had not respect. And Cain was very wroth, and his countenance fell.
Clearly, man’s way (CAIN’S OFFERING) was opposed to God’s way (ABEL’S OFFERING)- and it still is today. “Man says, “Do!” God says, “Done!” Man says, “Toil!” God says, “Trust!” Man says, “Behave.” God says, “Believe!” Man says, “Achieve!” God says, “Accept!” Cain, who founded the world’s first false religion, said, “I’ll bring the fruits of my own good works.” His brother Abel said, “I’ll sacrifice a lamb without blemish.” Cain’s religion emphasized beauty. Abel’s emphasized blood. Cain’s only compounded the curse; Abel simply claimed the Cross. Cain’s religion produced a murderer; Abel’s faith produced a martyr. Cain’s religion looks fine to man and Abel’s faith seems folly to man. Cain’s religion illustrates man’s thoughts and man’s ways. Abel’s offering illustrates God’s thoughts and God’s ways. God is neither foolish or weak- He only seems so to self-inflated, ego-centered, Christ-rejecting men.” (John Phillips, Exploring First Corinthians)
