Have you ever had blurred vision? You try to focus on a single object but it looks like multiple objects. This is why the Trinity is such an unhelpful concept for focusing on God. It gives a blurred image of God – multiple images instead of one. Of course, you would expect an unbiblical doctrine to be unhelpful. And the Trinity is just such an unbiblical doctrine.
If you want to focus clearly on God, focus on Christ. Christ the Lord. He is “the image of the invisible God” (Colossians 1:15), “the exact representation of His nature” (Hebrews 1:3).
Christ (i.e. Messiah) was promised by God through many prophets across many generations, all long before He was ever born. Everything He did for us (teaching us, suffering for our sins, rising from the dead) was prophesied in the Scriptures well in advance. We may therefore be sure that He is the plan of God for our future.
Focus on Christ. In Him you will have a clear view of God. There is no need to blur your focus.
