Question: "What is agnosticism?"

Answer: Agnosticism is the view that the existence of God is impossible to be known or proven. The word agnostic essentially means without knowledge. Agnosticism is a more intellectually honest form of atheism. Atheism claims that God does not existan unprovable position. Agnosticism argues that Gods existence cannot be proven or unproven, that it is impossible to know whether or not God exists. In this, agnosticism is correct. Gods existence cannot be empirically proven or disproven.

The Bible tells us that we must accept by faith that God exists. Hebrews 11:6 says that without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him. God is spirit (John 4:24) so He cannot be seen or touched. Unless God chooses to reveal Himself, He is invisible to our senses (Romans 1:20). The Bible declares that the existence of God can be clearly seen in the universe (Psalm 19:1-4), sensed in nature (Romans 1:18-22), and confirmed in our own hearts (Ecclesiastes 3:11).

Agnostics are unwilling to make a decision either for or against Gods existence. It is the ultimate straddling the fence position. Theists believe that God exists. Atheists believe that God does not exist. Agnostics believe that we should not believe or disbelieve in Gods existence, because it is impossible to know either way.

For the sake of argument, lets throw out the clear and undeniable evidences of Gods existence. If we put the positions of theism and agnosticism on equal footing, which makes the most sense to believe in regards to the possibility of life after death? If there is no God, theists and agnostics alike all simply cease to exist when they die. If there is a God, both theists and agnostics will have someone to answer to when they die. From this perspective, it definitely makes more sense to be a theist than an agnostic. If neither position can be proven or disproven, it seems wise to make every effort to thoroughly examine the position that may have an infinitely and eternally more desirable end result.

It is normal to have doubts. There are many things in this world that we do not understand. Often, people doubt Gods existence because they do not understand or agree with the things He does and allows. However, as finite human beings we should not expect to be able to comprehend an infinite God. Romans 11:33-34 exclaims, Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out! Who has known the mind of the Lord? Or who has been his counselor?

We must believe in God by faith and trust His ways by faith. God is ready and willing to reveal Himself in amazing ways to those who will believe in Him. Deuteronomy 4:29 proclaims, But if from there you seek the Lord your God, you will find Him if you look for Him with all your heart and with all your soul.
