Here is something really obvious, yet many do not understand it.
If you soak a sponge in vinegar, then you can extract vinegar from a sponge. But if you do not soak vinegar in a sponge, then you will extract that which is originally in the sponge. Likewise, if you start with your mind being convinced of a doctrine, then no matter what the evidence against it, you will find a way to point it to your doctrine. And so it is if you start with the Trinity Doctrine, then you will twist scripture toward the Trinity and ignore all the scriptures that you cannot twist.
In the same way, if you start with a belief that there is no God, then all science will point you to there being no God. It is called starting with the conclusion or having your mind already made up. Instead, we need to let evidence lead us to the conclusion, anything else is bias.
What would happen if you started with humility and read the scriptures so as to learn the truths of God contained within? You would then renew your mind and with that renewed mind, you could gain an ever-increasing depth of understanding in scripture, enabling you to consume the meat of the Word, and to rightly divide the Word. This would further enable you to teach the word with all faithfulness toward God and with a good conscience.
