We do not take Jacob as an example of what man should do in his finances, for he was something of a trickster. He represents the world in its trickery and cunning in finances. But apparently Jehovah, the one Mind, was with him. (Sometimes there are contradictions that we cannot understand.) When we know that we are the directive power as regards all that belongs to us, we may get on financially; however, in the end we have to account to infinite Mind.
But with it all, Jacob loved Jehovah and shared his wealth with the Lord. He proved the law of tithing, that tithing is one of the foundation principles of financial increase. Man can become a great possessor of the substance of this world if he follows certain rules of tithing. Jacob gives us the key, which is the recognition that God is part of all substance, and that if man wants to handle substance wisely and well, if he wants to handle it for great financial success, he should do what Jacob did: take God into partnership with him.
There is an omnipresent financial Mind, and if man begins to deal with this financial Mind he will have a partner that has all resources at His command.
If you want to become a rich man, if you want to be possessed of every good thing in the world, take God as your partner, incorporate His mind into your mind, in your daily giving. Give of your substance with the thought that it is God's money you are handling. Realize that it is His tenth that
