A covenant is a two-way commitment or promise between man and God.
If we covenant to do the things the Lord asks us to do, he enters into the
process and commits Himself to us. In covenanting we not only marshal
and energize the powers within ourselves; we also release in our behalf the
powers of the God of Heaven. In such a covenant, heaven is moved and
new energies are generated in the mortal covenant maker.
