I found something Piper said regarding how one comes to trust in the truth of the Bible to be helpful. He distinguishes between God "'telling us' that the Bible is true" and "enabling us to see what is really there." He writes,
The practical effect of this path is that I do not ask you to pray for a special whisper from God to decide if Jesus is real. Rather I ask you to look at the Jesus of the Bible. Look at him. Don't close your eyes and hope for a word of confirmation. Keep your eyes open and fill them with the full portrait of Jesus provided in the Bible. If you come to trust Jesus Christ as Lord and God, it will be because you see in him a divine glory ad excellence that simply is what it is - true. (Seeing and Savoring Jesus Christ, p.121)This does not diminish the work of the Holy Spirit, who helps us see this truth. It does speak against the idea that we should pray for some sign or magical change in ourselves that will make us all of a sudden believe in something that a logical person would find unbelievable. You don't trust and follow someone unless you know them; you don't know them unless you take the opportunities to do so.
Does this resonate with you? Is what Piper says helpful?
