The Feast of Tabernacles is a memorial of transitoriness and impermanence, commanded in Leviticus 23 so that each generation remembers God made Israel dwell in booths after bringing them out of Egypt. The temporary dwellings are the heart of the Feast, and skipping them misses its main point. They keep God's people slightly off balance, humbling them as a king's palace would not, and remind them that nothing on earth is permanent and that trust must rest on what God is doing. The booths were attractive and sufficient, built of lush branches, yet as the green leaves dried day by day, they showed the relentless march of time and the intrinsic weakness of all things physical, as well as dependence on God to keep the roofs from blowing away. God does not demand asceticism, but He rarely grants every wish, since perfect circumstances would lead people to forget Him. Believers are pilgrims who give up some material stability to follow God to a far better destination. Paul and Peter call the physical body a tent, adequate for the pilgrimage but limited, lasting roughly seventy or eighty years. Solomon concluded that life focused only under the sun is vanity, but life focused above the sun can rejoice in God's gifts as preparation for something better. Jesus Christ, the Creator, put on a temporary tent of flesh and tabernacled among men, proving His willingness to supply every need in temporary circumstances while bringing believers to a life that is no longer temporary but eternal.

Everything physical is passing away, including our frail bodies, and God has subjected creation to futility in hope so that we will see the contrast and choose what is permanent. Life measured against eternity is a mere vapor, a shadow, grass that flourishes in the morning and withers by evening (James 4:14; Job 14:1-2; Psalm 90; Psalm 103:15-16; Isaiah 40:6-8; I Peter 1:24-25). Aging, the loss of the senses, and mortality itself show that every person has an expiration date, and willful sin makes that mortality permanent. Hebrews 1:10-11 says the heavens and earth will perish and grow old like a garment, while God remains unchanged. Solomon's Ecclesiastes records the disillusionment that comes from pursuing worldly pleasure, since all under the sun is vanity. The temporary booths of the Feast of Tabernacles picture our fleeting, mixed earthly pilgrimage. Even the wicked and the governments of this world vanish like smoke, but God's Kingdom lasts forever. God is the Rock, a symbol of firmness, stability, and faithfulness, and even boulders that survive wildfires only faintly picture His permanence. The remedy is to number our days and gain a heart of wisdom (Psalm 90:12), to turn our focus from perishable things to the eternal, and to seek first God's Kingdom and righteousness (Matthew 6:33). Knowing God is eternal life (John 17:3), and the godly character built now by His Holy Spirit is the one thing that passes through the grave.

Living in temporary booths at the Feast teaches a sense of impermanence. This world seems permanent, real, and solid, but it is not the Christian's inheritance; the inheritance is the world to come. Abraham, Isaac, and Jacob lived in tents for long lives, owned no land except their burial plots, and confessed themselves strangers and pilgrims who looked for the city with foundations whose builder and maker is God (Hebrews 11:8-10). Moses, David, the prophets, the apostles, and the Church itself have lived unsettled lives, moving from place to place. Jesus Himself had nowhere to lay His head (Luke 9:57-58). A settled life is rare for God's people, and Christians should expect turmoil, tests, and trials as normal. Anyone expecting a settled existence in this present evil world is in for disappointment. Paul says the outward man is perishing while the inward man is renewed daily, and he directs believers not to look at the things which are seen, for they are temporary, but at the things which are not seen, for they are eternal (II Corinthians 4:16-18). God wants eyes fixed beyond what can be seen and felt, looking forward to being truly settled in the Kingdom of God. Yet the booth is not a place of privation, since the Feast is a time of abundance and enjoyment. It reminds God's people that they are in transit, led by a faithful Guide toward a better place, and that the hardships and unsettledness of the journey will be forgotten when they enjoy eternal life.
