We rob ourselves of so much of the glories and the riches of grace when we fail to take the trouble to understand these things [the great doctrines of Scriptures] and to face the teaching of Scripture. […]
Some even try to excuse themselves by saying that they are not interested in theology and doctrine. Instead, they want to be “practical” Christians and to enjoy Christianity. But how terribly wrong that is! The Scripture gives us this teaching, the Apostle Paul wrote these letters that people like ourselves might understand these things.
Some of the people to whom Paul wrote were slaves who had not had a secondary or even a primary education. We often say that we have not the time to read – shame on us Christian people! – the truth being that we have not taken the trouble to read and to understand Christian doctrine. But it is essential that we should do so if we really desire to worship God.
If there is no praise in a Christian’s life it is because he is ignorant of these things. If we desire to praise God, we must look at the truth, and expand our souls as we come face to face with it. If we want to say “Blessed be God” from the heart we must know something about how He has planned this great salvation.
