Agnosticism (from Greek a ‘without’ + gnosis ‘knowledge’) is the belief that nothing is known or can be known of the existence or nature of God. Therefore, agnostics are people who feel that God’s existence cannot be proved.
I have already showed from the Scripture (in the refutation of atheism) that the existence of God can be proved in various ways. However, I would like to say something else. Man can not only know that God exists, but also know Him personally. In other words, He can have a personal relationship with God. For Jesus Christ said: “All things are delivered to me of my Father: and no man knoweth who the Son is, but the Father; and who the Father is, but the Son, and he to whom the Son will reveal him” (Luke 10:22). Therefore, God the Father can be known through His Son, there is no other way to know God. Thus, in order to know God a man needs to know His Son. How can one know the Son of God then? By repenting of his sins and believing in His atoning sacrifice and His resurrection.
I am by the grace of God among those who know God. However, I would like to make it clear that God cannot be perfectly known by our imperfect mind. I mean, we can’t know all His purposes, all His ways, all His judgements, all His thoughts, for the Scripture says: “Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgements and His ways past finding out! For who has known the mind of the Lord?” (Romans 11:33-34 – NKJV) and also: “Can you search out the deep things of God? Can you find out the limits of the Almighty? They are higher than heaven – what can you do? Deeper than Sheol – what can you know? Their measure is longer than the earth and broader than the sea” (Job 11:7-9 – NKJV).
In conclusion, one can know God but not through his understanding or reason or through philosophy or some so called science, but only through repentance and faith in the Son of God. We are among those who know God, and even though we know that our knowledge of God is partial, as it is written: “We know in part” (1 Corinthians 13:9 – NKJV), we have the firm confidence that one day we will know God just as we also are known by Him. We have an altar on which we offer our spiritual sacrifices, but not an altar with the inscription ‘to the unknown or unknowable God’ but with this inscription ‘to the God we have known and whom can be known through Christ Jesus, His Son’. To Him be the glory now and forevermore. Amen.
Beware of agnosticism and refute it, for it is a wrong belief, which is used by that ancient serpent to keep millions of people far from the true and living God.
