Psalms 34:8

O taste and see that the Lord is good - Apply to him by faith and prayer; plead his promises, he will fulfill them; and you shall know in consequence, that the Lord is good. God has put it in the power of every man to know whether the religion of the Bible be true or false. The promises relative to enjoyments in this life are the grand tests of Divine revelation. These must be fulfilled to all them who with deep repentance and true faith turn unto the Lord, if the revelation which contains them be of God. Let any man in this spirit approach his Maker, and plead the promises that are suited to his case, and he will soon know whether the doctrine be of God. He shall taste, and then see, that the Lord is good, and that the man is blessed who trusts in him. This is what is called experimental religion; the living, operative knowledge that a true believer has that he is passed from death unto life; that his sins are forgiven him for Christ's sake, the Spirit himself bearing witness with his spirit that he is a child of God. And, as long as he is faithful, he carries about with him the testimony of the Holy Ghost; and he knows that he is of God, by the Spirit which God has given him.
