Timeless truths about beliefs. What you believe is more important than what you do! Why? Because what you do is based on what you believe. God has determined that what you believe sets your eternal destiny. Only you decide what you will believe.
Paul writes a tremendous theological discourse in the first eleven chapters of Romans. Then in chapter twelve he basically says, based on all I have shared with you, here is the appropriate action! Belief determines behavior. We do what we do because of our values. The value we place on something is determined by what we believe.
The church in America has become shallow in doctrine; therefore, the church is shallow in behavior. We must know what we believe, why we believe it, and evaluate our actions based on our beliefs. Actions always reveal beliefs! We can hide behind words that espouse a belief but our actions removes the curtain.
