What is so important about doctrine? Doctrine tells us about God. It tells us who God is, what God has done and what God will do. Without knowing God we cannot be intimate with God. When we desire to be intimate, it is a natural presumption that we know that person extremely well. The problem we have today is that there are those that have no clue about who God is nor what God desires.
This lack of understanding means that we cannot be intimate with God.
We should ask ourselves – Who Is God. There are more and more people today that accept pagan god’s that are not gods and say that these gods are all the same and we worship the same god. This statement comes from ignorance. The answer is simple – God is Yahweh, the one (Deut. 6:4), ultimate (Psalm 97:9; Isaiah 40:12-31), eternal Being (Psalm 90:2), who created (Genesis 1:1), rules (Psalm 115:3), and sustains all that exists (Job 38; Acts 17:24-28).
Countless religious substitutes divert worship to themselves. But there is only one Creator and Savior. Because He alone gives life, he deserves our gratitude. Because every heartbeat and circumstance is under His control, He alone deserves the trust that we habitually place in ourselves, our family, or our finances. Because He is eternal, no one will outlive Him. Because He is the Lord of lords, he is the only one in the universe to whom we must finally answer.
How do we know there is a God? The wonders of nature witness to His existence as Creator (Psalm 19:1-4). The inner voice of our conscience testifies to His existence as Lawgiver and Judge (Romans 1:18-32; 2:12-16). And the love of Christ reveals His existence as Savior and Friend (John 1:1-18; 15:15).
Because God has made Himself self-evident, our problem is not so much to prove His existence as to stop ignoring it (John 3:17-21).
How can we define or describe God? God is the one and only (Isaiah 44:6), unchangeable (James 1:17), invisible (Col. 1:15), infinite (I Kings 8:27), and perfect (Matt. 5:48) Spirit Being (John 4:24). He is holy (I Peter 1:15,16), loving (I John 4:8-16), and truthful in all that He does (John 3:33). he has lived from all eternity as one God in three distinct persons (Matt. 28:19), and in the course of time He visited us as God in the flesh (John 1:1-14).
He exists with or without our understanding. he can be described truthfully and adequately, but never exhaustively. he is infinitely more, and never less, than we have yet known Him to be.
The most apt and studious scholar has not plumbed the depths or climbed the highest in knowledge of God. We have not touched on those emotions of God such as love, hate, jealousy, anger and other emotions. We have not discussed the plans and desires of God, we have merely skimmed the surface. It is ridiculous to say we love God and desire to be intimate with Him when we only have a shallow knowledge of Him.
