God created the world, yet humankind discriminates against Him. We cannot in good conscience pay to educate children that God's Word is not true and cannot be trusted. Their familiar association also brings them into temptation that should be avoided. Much of the country's woes regarding unwed mothers and welfare can be traced directly to this.

Public schools are Godless by federal law. You may pass out condoms but not Bibles. You may speak about spiritualism and celebrate satanic holidays such as Halloween, but not the truth as is found in God's Word. We are not saying that public schools should be a place to teach the Bible, but they should not exclude the truths that are in the Bible. Public schools may allow individuals to go into a room and pray if they like, but the system of itself is against the true things of God.
