The contribution is on the one hand a commandment of the LORD, on the other hand He asks everyone to bring the contribution with a willing heart. Everyone born of God has the Lord Jesus as his life. By this he loves God. It is his joy to serve him and obey his commandments. The commandments of God – that is not the law of the ten commandments, but all that is inherent in the new life, as it is perfectly visible in the Lord Jesus – are not heavy for those who love Him (1Jn 5:33For this is the love of God, that we keep His commandments; and His commandments are not burdensome.).
The description of the materials is the same as in Exodus 25 (Exo 25:4-74blue, purple and scarlet [material], fine linen, goat [hair],5rams’ skins dyed red, porpoise skins, acacia wood,6oil for lighting, spices for the anointing oil and for the fragrant incense,7onyx stones and setting stones for the ephod and for the breastpiece.). This is not a pointless repetition. When God repeats something, it makes it even clearer how much importance He attaches to it and we realize the value it has for Him. He wants us to share in His feelings and in patience He provides everything we need. That also includes repetition.
The materials all speak of the Lord Jesus. Bringing it means telling God what we have found in the Lord Jesus. This is an act of the whole people. Everyone has their own contribution, but all contributions together are needed for the dwelling place of God. The dwelling place of God is established where His people honor Him. He is “enthroned upon the praises of Israel”, His people (Psa 22:3b3Yet You are holy,
O You who are enthroned upon the praises of Israel.
