Ever since man soiled himself with sin in the Garden of Eden, God has been in the washing business. Immediately the first-couple sinned, God shed blood in slaying an animal to make skin-clothes to cover their nakedness. But their offspring continued soiling themselves dirty, so God introduced new washings; whereby a lamb would be slain as a sin-offering. But these could not cover nor erase the sinfulness of man. Even though the lamb-offering was annual, covering sins for a year; man’s transgression did not abate. He still went out to play and always came back dirty.
So as a permanent solution, God finally introduced a new type of wash which would guarantee better results for eternity. He opted to do away with animals’ blood and chose to go with a man’s. But because all earthly men had sinned and fallen short of His standards, God opted to use the blood of a heavenly man – Heb 9:11-15. This great act was done and duly recorded in The Bible where it declares that Jesus washed us from our sins in His own blood - Rev 1:5.
It would have been okay for God to sprinkle or just dip us, but He opted to go through the tedious motions of washing. And He used the best wash available - the blood of His son. The best detergents are usually used to clean the most valuable items. The more an item is worth; the more expense is incurred in its cleansing. So for God to deem it fit to wash man with the blood of His son, then man must be worth much more than he actually knows.
If the only detergent which could remove the stain of sin was the blood of God’s son, then God knows something about sin that we don’t know. It means that sin is quite harmful and nothing should be spared to erase it from man. So man should strive to stay cleansed and believe that him whom the Son-of-God has washed clean must be clean indeed.
It is needless to doubt whether God’s detergent did a good job. Just be fully-persuaded that once one receives Christ into his life, he is sanctified wholly - spirit, soul and bod - 1 Thess 5:23. All doubters should read God’s detergent ad displayed in Isaiah 1:18 saying “Come now, and let us reason together. Though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall be as wool. God still has the best detergent in the market – it washes whiter and brighter for longer.
