Charles Spurgeon Commentary Deuteronomy 6:3-4

"Hear therefore, O Israel, and observe to do it; that it may be well with thee, and that ye may increase mightily, as Jehovah, the God of thy fathers, hath promised unto thee, in a land flowing with milk and honey. Hear, O Israel: Jehovah our God is one Jehovah:" — Deuteronomy 6:3-4 (ASV)

Hear therefore, O Israel, and observe to do it; that it may be well with thee, and that ye may increase mightily, as the LORD God of thy fathers hath promised thee, in the land that floweth with milk and honey. Hear, O Israel: The LORD our God is one LORD:

There is but one God. This is the very basis of our faith; we know nothing of "gods many and lords many." Yet it is the Triune God whom we worship; we are not less Unitarians in the highest meaning of that word because we are Trinitarians. We are not less believers in the one living and true God because we worship Father, Son, and Holy Spirit.
