Psalm 111:10 The fear of the Lord is the beginning of wisdom; A good understanding have all those who do His commandments. His praise endures forever.
Understanding God comes from understanding the Bible and applying what we understand into our lives.
Knowing the rules and regulations in anything in life is not much good until you follow them, obey them and apply them into your life.
God has been very specific through the Bible and we need to know what He says about things.
But not matter how much we may get wrong, He still deserves all the praise for being right!
