The first Essential Belief of Faith Baptist Church is “We believe in one God, maker of heaven and earth, and eternally existent as God the Father, God the Son, and God the Holy Spirit.”
The most important thought that could ever come across the minds of any human being is the thought of God. God gave people the capacity to think and speak and the greatest one word in any language that can be thought or spoken is the word for ‘God.’
The worst sin that could be committed by any human heart or body is the sin of idolatry. It is the most hateful to God. Idolatry is to place anything in the place of God. The heart that chooses to commit idolatry tries to find a substitute for the true God – to see God other than He is. How often we try to create a ‘god’ after our likeness, not what He has revealed to us about Himself. Idolatry seeks to conform God into an image like we think He ought to be. It is just as much idolatry to think of God other than He is, than to make Him out of a stone or piece of wood. Either way, it is not God.
Our society thinks we have progressed from those ancient societies who worship gods of rock and nature. But idolatry begins in the mind before it can be acted out. Paul wrote, “When they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.” (Romans 1:21) Then they made images of the gods they chose to worship. The worship of “birds and beasts and creeping things” began in the mind. A wrong idea about God is the well from which the stream of polluted idolatry flows. All the branches of idolatry finds its root in a wrong thinking of God.
It is the obligation of Christians and churches to uphold the truth about God as revealed in His Word. It is not enough to say, “I think God is…” We must answer “God tells us He is….” To create a God the way we would want God to be is to set up a god of our own creation and design – a false idol. And God will destroy all idols and images that compete for our total allegiance.
So what is God like? A. W. Tozer so aptly said, “…it cannot be answered except to say that God is not like anything; that is, He is not exactly like anything or anybody.” Christian theologians and common Christians have searched the Scriptures to deduce what God is like. We must know about Him so we can worship Him as He is. Jesus Himself said, “God is Spirit; and they that worship Him must worship Him in spirit and in truth.” (John 4:24).
It will be impossible to make a complete list of the attributes of God in this post. One of the 
books in my library is The Existence and Attributes of God by Stephen Charnock. It is over 1,100 pages and took my nearly a year to finish reading. Even this book could not exhaust all that could be said about God. My favorite book about God (besides the Bible) is the small The Knowledge of the Holy by A.W. Tozer (only 124 pages). You can get the Kindle version for 99 cents (click here). I want to share a few thoughts by the author about some of the attributes of God. My hope is these will help you understand who God is and love Him more.
About the Self-existence of God: “God has no origin, said Novatian, and it is precisely that concept of no-origin which distinguishes That-which-is-God from whatever is not God… God is self-existent, while all created things necessarily originated somewhere at some time. Aside from God, nothing is self-caused… Man is a created being, a derived and contingent self, who of himself possesses nothing but is dependent each moment for his existence upon the One who created him after His own likeness. The fact of God is necessary to the fact of man. Think God away and man has no ground of existence.”
About the Self-sufficiency of God: “Whatever God is, and all that God is, He is in Himself. All life is in and from God, whether it be the lowest form of unconscious life or the highly self-conscious, intelligent life of a seraph (angel). No creature has life in itself; all life is a gift from God…. The problem of why God created the universe still troubles thinking men; but if we cannot know why, we can at least know that He did not bring His worlds into being to meet some unfulfilled need in Himself, as a man might build a house to shelter him against the winter cold or plant a field of corn to provide him with necessary food. The word necessary is wholly foreign to God.”
About the Love of God: “From God’s other known attributes we may learn much about His love. We can know, for instance, that because God is self-existent, His love had no beginning; because He is eternal, His love can have no end; because He is infinite, it has no limit; because He is holy, it is the quintessence of all spotless purity; because He is immense, His love is an incomprehensibly vast, bottomless, scoreless sea before which we kneel in joyful silence and from which the loftiest eloquence retreats confused and abashed…. the love of God is one of the great realities of the univers, a pillar upon which the hope of the world rests. But it is a personal, intimate thing, too. God does not love populations, He loves people. He loves not masses, but men. He loves us all with a mighty love that has no beginning and can have no end.”
You can know God through Jesus Christ. Knowledge of God is not gained by studying alone. It comes by having a personal relationship with Jesus Christ.
