Partner With Us

Help us share the Gospel!

Printed course and printed diploma fee information/payment methods are on their respective pages.

If you have been taught the Word of God through our ministry, or if you simply have a mind to support the preaching of the Gospel and discipling of believers in the Lord, we welcome your partnering with us according to God's plan!

Because of the task that God has given us to freely distribute this material around the world, any gift you send will have an eternal impact!

"Do you not know that those who are employed in the temple service get their food from the temple, and those who serve at the altar share in what is sacrificed on the altar? In the same way, the Lord commanded that those who proclaim the Gospel should get their living by the Gospel" (I Corinthians 9:13, 14).

"But the one being taught in the word must share with the one teaching in all good things" (Galatians 6:6).

Expecting a Harvest

God will richly bless you for your obedience, and we thank you for your love and support! When you take Yahweh at His Word, great things will happen! Look at these verses which encourage the believer to give, that it may be given back!


"Give, and it will be given to you. A good measure, pressed down, shaken together, running over, will be put into your lap; for the measure you give will be the measure you get back" (Luke 6:38).


"But the one being taught in the word must share with the one teaching in all good things. Do not be deceived; God is not mocked, for you reap whatever you sow. If you sow to your own flesh, you will reap corruption from the flesh; but if you sow to the Spirit, you will reap eternal life from the Spirit. So let us not grow weary in the well doing, for we will reap at harvest time, if we do not give up. So then, whenever we have an opportunity, let us work for the good of all, and especially for those of the family of faith" (Galatians 6:6-10).


"The point is this: the one who sows sparingly will also reap sparingly, and the one who sows bountifully will also reap bountifully" (II Corinthians 9:6).
