1. Keep the Sabbath (1-3)
Even though they were going to do God's work and build God's house, they had to keep the Sabbath. Nothing is more important than worshiping God on his day.
2. Offer with a willing heart (4-29)
The people had sinned and repented. They had tasted God's mercy and forgiveness. Their hearts were full of thanksgiving. Moses gave them the privilege of making freewill offerings to God. They could offer the necessary materials for making the tabernacle and the priests' garments and/or skills. Their hearts were moved to offer their most precious things.
3. Spirit-filled workers (35:30-36:7)
God filled the master craftsmen, Bezalel and Oholiab, with his Spirit and gave them the necessary gifts to build the tabernacle and all of its accouterments. They and all the other skilled workers worked with glad and willing hearts. The people brought more than enough to complete the work.
Application: Lord, help me to serve you with a repentant, joyful and willing heart.
One Word: Life, time, materials are God's
