We Love God!

God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)

True enthusiasm comes from being filled with the Spirit, and as we strive to do that to which we know God has called us, in conscious dependence upon Him, we will then be able to convey our excitement to others and carry them with us (Derek Prime and Alistair Begg).

I care not where I go, or how I live, or what I endure so that I may save souls. When I sleep I dream of them; when I awake they are first in my thoughts…no amount of scholastic attainment, of able and profound exposition of brilliant and stirring eloquence can atone for the absence of a deep impassioned sympathetic love for human souls.
