True and saving religion is not so much a knowledge of God and of divine things as the life of God in the soul of man. Everything is best and most known by what best and most resembles it, and therefore so much stress is laid in Holy Scriptures on a truly Christian life; and our Lord says, He that hath my commandments and keepeth them, he it is that loveth me. True religion comes from the eternal light even from Him who says of himself I am the light of the world, and therefore, like the sunbeam, it not only enlightens but warms and enlivens. Saint Paul, opening out the right way of becoming wise unto salvation, says knowledge puffeth up, but charity edifieth. That Christianity which is only learnt from creeds and confessions of faith, is but a poor, weak light; but the powerful working of a true and saving knowledge of God and of Christ within the soul by the Holy Ghost, shows itself in purity of heart and life. Therefore our Lord says, Blessed are the clean of heart, for they shall see God. Seek God and your Saviour, then, in your own souls, for that is the best, the truest, and only saving knowledge of Him, which is kindled within our hearts by the heavenly warmth of the Holy Spirit. Of this knowledge we are to understand Christ's words, This is eternal life, that they may know Thee, the only true God, and Jesus Christ whom Thou hast sent. For this, as a present, a daily, and hourly salvation, ask and it shall be given you, seek and you shall find, knock and it shall be opened to you. The promise is express, that God will give the Holy Spirit to them who ask.
