The Law of Love and the sin of unbelief

The Law of Love<br />…22Keep your belief about such matters between yourself and God. Blessed is the one who does not condemn himself by what he approves. 23But the one who has doubts is condemned if he eats, because his eating is not from faith; and everything that is not from faith is sin. <br /><br />Romans 14:5<br />One person regards a certain day above the others, while someone else considers every day alike. Each one should be fully convinced in his own mind.<br /><br />Titus 1:15<br />To the pure, all things are pure; but to the defiled and unbelieving, nothing is pure. Indeed, both their minds and their consciences are defiled.<br /><br />Romans 14: 23 And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
