The two-primary reasons Messiah Jesus left the Eternal Realm and entered the temporary Realm of Time…

First and foremost,

Messiah Jesus entered Time “to destroy the works of the devil” via a battle strategy known as The Gospel, a Gospel of grace, faith, initiated by Elohim’s selfless love demonstrated at Golgotha, a battle strategy that was ordained “before Time began” (1 John 3:8b; 2 Timothy 1:8-10).

Second,

In order for Messiah’s mission “to destroy the works of the Devil” to be successful, Jesus came to fulfill the law…every moral law that prevents humanity from entering the Kingdom due the Adamic curse (Romans 5:12; Matthew 5:17) thereby offering humanity the opportunity to attain victory over the Devil via imputed righteousness (2 Corinthians 5:21).

Jesus fulfilled the law, all law, in perfection as mandated (James 2:10; Galatians 3:10) if one is to attain righteousness through law-keeping; in other words, Jesus did for us what we could not do for ourselves…Jesus walked in sinless perfection before the Father and the one who “believes” with a sincere heart that Jesus is Messiah who died for them will receive the sinless perfection of Jesus gifted-imputed over their life in exchange for their sin (2 Corinthians 5:21) and the Father agrees by covenant promise to declare that person “not guilty,” forever (Hebrews 8:12); this, as the Holy Spirit is gifted the redeemed as the Guarantor of New Covenant relationship with the Father (Ephesians 1:13-14).

Torah Law and the New Covenant,

Torah’s relevance, its purposes, in the Realm of Time have come and gone as Torah Law, Sinai, was given as a tool of sanctification for the Hebrew Tribes, a bulwark against moral compromise with paganism; Torah was also a divine roadmap showing the Way to life in Messiah but Torah was NEVER the destination (Galatians 3:24; 2:16).

The New Covenant offers a radically different application of law through the Spirit, the spiritual law written upon the heart arbitrated by the Spirit via the redeemed conscience (Romans 7:6); the “law of the Spirit of life” in the New Covenant is vastly and eternally superior to the “law of sin and death” (Torah).

It is the spiritual law in the New Covenant working through the redeemed conscience arbitrated by the indwelling Holy Spirit via daily sanctification that is infinitely superior to a written code mandating perfect compliance from the old sin-nature that could never comply in mandated perfection (Romans 8:1-11; Galatians 3:10; James 2:10; Romans 7:6).
