Way back when I was a Freshman in college I used to watch Perry Mason every day at noon in the “Student Union” building right after I ate lunch at 11:30 am. There were about 20 of us crammed into the TV room watching every day. About half way through the program we would start debating who the real killer was, those were real mysteries.
The Bible talks about mysteries, things or information hidden from us, or things just too difficult for us to grasp fully. One of the mysteries is God in the person of Jesus Christ becoming man, 100% flesh, exactly like us in every way. He even experienced conception, growing as an embryo, being born as a helpless baby, helpless in every way as we all were. As a child, he grew in stature; he grew in wisdom, he learned skills, the verses that he quoted to the devil he had to memorize. Jesus got tired, he got discouraged, he got angry, and he got hungry.
Philippians 2:6-7 who, although He existed in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men.
Hebrews 2:17 Therefore, He had to be made like His brethren in all things, so that He might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people.
Hebrews 4:15 For we do not have a high priest who cannot sympathize with our weaknesses, but One who has been tempted in all things as we are, yet without sin.
1 Timothy 3:16 By common confession, great is the mystery of godliness: He who was revealed in the flesh, Was vindicated in the Spirit, Seen by angels, Proclaimed among the nations, Believed on in the world, Taken up in glory.
The only way that anyone can understand the mysteries of God is for God to make them clear to us, and He does that for those who want to know the answers. If we seek Him and His truth, He will make it clear to us.
