There are a number of different ways God could have allowed the Messiah, Christ Jesus, to die physically – stabbing, beheading, etc. – and still deliver us from our bondage to sin and death. So why did God want it to happen on a cross? Was God speaking something more to mankind through this visible, physical method of death? Absolutely!
In the Garden of Eden “sin” was represented as “fruit hanging on a tree”. Eve ate the forbidden fruit, which brought on the curse of death. God wanted Christ’s physical body to be a visible picture of this original “curse of sin” when he died; thus, he hung him like fruit on a tree! The only difference was … Jesus NEVER sinned! Thus, his spiritual death became the righteous death whereby we can now have our death penalty (for the sins we’ve committed) paid in full. His death in place of our death! The righteous for the unrighteous! Praise his name forevermore!
In addition, by having Christ’s two physical hands (10 fingers) and his two physical feet (10 toes) BOTH nailed to the tree … God was saying, “This man’s death is a worthy sacrifice, having power to pay for ANY and ALL sin (10LC disobedience)!” Listen, in Scripture, God often says and does the same thing twice – Joseph’s 2 dreams, Jacob working 7 years twice for a bride, etc – and this is always God’s way of signifying the “thing” is SURE! It is coming to pass! It cannot be changed! Subsequently, we have God’s reason behind wanting TWO sets of the 10LC tables (hands and feet!) being nailed to the tree (cross). God was saying the same “thing” twice, “My work of salvation is FINISHED!”
“Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree” (Galatians 3:13)
“For he (God) hath made him (Jesus) to be sin for us, who knew no sin; that we might be made the righteousness of God in him” (II Corinthians 5:21)
“But IF we walk in the light, as he (God) is in the light, we have fellowship one with another (God with us, and us with God), and the blood of Jesus Christ his Son cleanseth us from ALL sin” (I John 1:7)
When Moses received the two stone tables (with the 10LC) from God on Mount Sinai the first set was broken, consequently God had to make another set. Do you think God wanted this to happen? If so, why? Is it possible God wanted to AGAIN make the connection at Mount Sinai between His Law of Love and the way in which He designed our physical bodies by creating TWO sets of the 10LC tables, mirroring our TWO hands & TWO feet?
Since your physical body has TWO sets of the 10LC tables, and since every thought, word, & deed you think, speak, & do is either in obedience or disobedience to the 10LC – you cannot have a thought, word, or deed outside of them! – and since you use your hands and feet to carry out these works, do you think your Judgment day sentencing will be SURE & UNCHANGEABLE?
