The Lord is near; have no anxiety. The Lord is always near to all who call upon his help with sincerity, true faith, sure hope, and perfect love. He knows what you need, even before you ask him. He is always ready to come to the aid of all his faithful servants in every need. There is no reason for us to be in a state of great anxiety when evils threaten; we must remember that God is very near us as our protector. The Lord is at hand for those who are troubled in heart, and he will save those who are downcast in spirit. The tribulations of the just are many, and the Lord will rescue them from them all. If we do our best to obey and keep his commandments, he does not delay in giving us what he has promised.
