Without a doubt, there will be sermons, teaching, and music which you may disagree with, or even oppose. There are many messages on this site that we don't totally agree with. There are songs where the lyrics aren't scriptural, there are articles which disagree with each other, and there are sermons that sometimes appear to teach conflicting ideas and truths. Why would we publish all of them?
The answer is actually quite simple, we don't know it all. The Bible tells us that we "see in a glass darkly" and we "know in part." There are certain fundemental truths that can never be negotiated away, such as the Virgin Birth of Jesus, the fact that Jesus is the only way to the Father, and that there is only one True God. There are many other "truths" that Christians fight over, and disagree about that simply are not fundamental in the way that God defines it.
We believe that all of the sermons in our library contain Bible teaching and truth which will help you grow into maturity. We expect our church family to be like the Christians of Berea who "examined the scriptures daily, to see whether these things [they heard preached] were so." (Acts 17:11).
As a brother said so long ago, we must "learn to eat the meat and spit out the bones." If you are looking for error-free preaching, we suggest that you wait for the return of the Lord Jesus, because men are fallible (even the Pope). Of course, the Bible commands men to preach, so God must be OK with some erroneous teaching every now and then. There is a HUGE difference between an occasional false teaching and a false teacher.
