Yoking
Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? (II Cor. 6:14)
Usually, only you and God know when it happens. Emotional yoking, unlike contractual yoking, occurs day by day and inch by inch. Take stock daily of your commitments and be sure you own your lifestyle and not the other way around.
