The Spirit of God, with skill, ability and knowledge

Exodus 31:1-18
God's servant filled with the Spirit of God, with skill, ability and knowledge in all kinds of crafts.
Obey my Sabbath, this will be a sign between me and you for the generations to come, so you may know that I am the Lord, who makes you holy.
When God chooses people for a particular work he also equips them to do it.
Spirit of God on verse 3 is one of the earliest references.
These craftsmen's skills are spiritual gifts for the service of God, and the names of the two go down in history.
Why?
God equips his chosen men for a particular work. First is the Holy Spirit, them the skill, ability and knowledge.
The way of Sabbath day of rest is kept is an index of the nation's spiritual health. Obedience in this is a test of their obedience to God in other ways too.
God gives everyone who follow him a sign between God and us. One is the tithe, and special miracle in our life.
How?
Thanks God give me sign and let me know God makes me holy, and God is my Lord for ever.
