All in Double Minded

Are we double minded, approaching our faith in one manner, while leading a different life in the world? On the Sabbath do we praise God, and say that we will put no other God before Him, then walk back into our homes and businesses placing our possessions, and gold, above all else? Do we pray fervently when desperate, but mumble mindless prayers over our meals each day when there is plenty? If we live in such a way as this we are lost indeed.
