Summary: The purpose of a tzitzit for a Jew is to remind of a relationship offer by God. The purpose of keeping a journal for a Christian is to remind a Christian of a relationship offer by God.
Grace to you and peace, from Him who is, and was, and who is to come.
Yeshua Hamashia (Jesus Christ) came as the anointed of Adonai (Lord and Master), El Elyon (The Most High God), El Olam (The Everlasting God), El Shaddai (Lord God Amighty), Elohim (God), Ha Shem, Jehovah Jireh (The Lord Will Provide), Jehovah Sabaoth (The Lord of Host), Jehovah Shalom (The Lord Is Peace), Yahweh (Lord Jehovah).
So many names because our creator is everything that is goodness and love in creation. Look at the public ministry of Yeshua. Scripture tell us what happened when He entered a village. The people would bring the sick so close they would reach out and touch the Tzitzit of his garment.
The Hebrew root origin for Tzit meant a blossom. The functional purpose of a fruit tree's blossom is to bring forth fruit. Hashem commanded in Numbers 15:37 and Deuteronomy 22:12; the observant men and women were to wear a tzitzit on the corners of their garments. This served a relationship purpose, you could tell an observant Jew from any other person. And for the Jew it was to remember the relationship God offered His chosen children.
The blossom of a fruit tree leads to bearing fruit. Fruit was likewise expected from the observant Jew wearing a tzitiz. The fruit would come as the faithful would be reminded of their relationship with Hashem. This remembrance should serve to protect observant Jews from the temptations of daily life. Giving into temptations, defile. While remembering a relationship with God, that should draw observant people to be obedient to God. Consider if we successful in rejecting the self serving pleasures in life?
After all the pharisees wore a tzitzit, their heart and eye was not seeking a relationship. Instead of a relationship, they wanted to judge regulations. Did Yeshua have errors and flaws that would feed their pride? They found none in him, but they celebrated discovering the errors of His disciples.
So it is today, with people among our families, neighborhoods, school or places of work. What flaws can I find in His disciples. May they instead see the relationship we have.
There was something else about the tzitzit. Scripture reveals to the sick, if they touched just his tzitzit they would be healed. Where did this idea come from? Why was it so believable the sick reached out touched and were healed?
Malachi 4:2 But unto you that fear My name shall the Shemesh Tzedakah sun of righteousness arise with healing in his wings; and ye shall go forth, and grow up as calves of the stall.
The Hebrew word interpreted as a wing of a bird also communicated the function for something at the corner of something. The tzitzit was attached at the corner of a garment. Malachi prophesied the Messiah would arrive with healing at his corners. Could Yeshua be God's promised anointed one?
Looking at that verse from Malachi we see not son of righteousness but sun of righteousness. The word for servant and the word for sun in the ancient Hebrew was the same. As the sun served the needs of the day, so the servant of righteousness would serve with healing in his corners. The corner of His garment is where his tzitzit would be. So touch the healing where he carried it. Have this relationship experience and be saved.
