True Christianity #295
295. The heavenly meaning of this commandment is that the Lord Jehovah is infinite, immeasurable, and eternal; and omnipotent, omniscient, and omnipresent. He is the First and the Last; the Beginning and the End; the One who was, is, and will be. He is love itself and wisdom itself, or goodness itself and truth itself. Therefore he is life itself. He is the sole being; all things come from him.
1 John 5:20-21
20
We know that the Son of God has come, and has given us an understanding, that we know him who is true, and we are in him who is true, in his Son Jesus Christ. This is the true God, and eternal life.
21
Little children, keep yourselves from idols.
