Twisting Interests

When we go to pray, we must not give the sacrifice of fools, that think not either what is to be done, or what is to be gained, but speak the words of the wise, who aim at some good end in what they say, and suit it to that end, we must have in our eye God's glory and our own true happiness; and so well ordered is the covenant of grace, that God has been pleased therein to twist interests with us, so that in seeking his glory, we really and effectually seek our own true interests. - Matthew Henry
