The Scriptures declare: yesh ohev davek me'ach – "there is a friend who sticks (davek) closer than a brother" (Prov. 18:24). His Name is Yeshua, the Holy One of Israel who descended to earth by clothing himself in human flesh. Yeshua demonstrated God's own devakut for us by "cleaving" to the cross as full payment for our sin. Because of His loyal love for us, we can now experience "at-one-ment" and communion with God (see John 17:21-23). Blessed be His Name forever.
The servant isn't above his master: We can't "out love" God. If He commands us to cleave to Him, then we can be assured that He is already cleaving to us. But love must be answered to be true love. In Modern Hebrew the word teshuvah, often translated "repentance," also means "an answer." It is the turning to a shelah, a question, and responding to it with complete honesty. God's love for us is the question, and our teshuvah – our turning of the heart toward Him – is the answer.
