Donate

Proverbs 23:23 urges us to spare no pains, cost, or sacrifice to obtain the truth, likewise wisdom, instruction and understanding. And after you have obtained it, keep it safe; do not barter it for earthly profit or the pleasures of sense.
I do not charge for ministering to you, but I do ask that you make a donation in accordance to Galatians 6:6:

Let the one who is taught the word share all good things with the one who teaches.
