Bring to the Lord freewill offerings for all the works

Exodus 35:1-29
Moses assembled the whole Israelite community and said to them to obey Sabbath regulations and take materials for the Tabernacle.
Everyone who was willing and whose heart moved him came and brought an offering to the Lord for the work on the tent of Meeting, for all its service, and for the sacred garments.
All the Israelite men and women who were willing brought to the Lord freewill offerings for all the work the Lord through Moses had commanded them to do.
These chapters record how the instructions given in chapters 25-31 are carried out to the letter. The craftsmen set to work, the people pour in their gifts, and the Tabernacle, its fittings and the priests' robes are all completed exactly as God has laid down.
Why?
God like the willing offering to the Lord and it is pleased to the Lord.
More important is execute the commandment of the Lord, not only knew or heard but do it as the Lord commanded.
How?
Do the word of the Lord and bring to the Lord freewill offering are the blessing to us.
