The issue you raise of inerrancy of Scripture is the most compelling issue in the Church (the entire Body of Christ scattered over the earth). This is because everything we believe is based on the fact that God said it and wrote it down in what has become our Bible. If it isn’t inerrent, we have no way of knowing if Jesus really was God or if we can actually be saved.
As the Bible explains it, “faith comes by hearing, and hearing by the Word of God”. If we approach the Bible as anything less than what it actually is – God’s Word, inerrant and perfect, we have cut ourselves off from faith. If you don’t really believe it is reliable, how are you going to be able to trust what it says about healing, about wellbeing, about the effectiveness of prayer, about holiness and all the other areas of life the Bible covers?
I’m not going to find fault with you for having doubts about the Scriptures. However, I will remind you that if you come down on the wrong side of the inerrancy question – whether you are eventually accepted by a group of like-minded people – you will have cut yourself off from access to faith and any sort of spiritual life with God.
Unless you think I’m being overly unfair here, put yourself in God’s position for a moment. Would you want to have fellowship with a person who calls you a liar even though you haven’t done anything that would support such a claim? Would you be interested in spending time with someone who says of you that you have given a false testimony concerning matters that are of the utmost importance?
Of course there is another important aspect to this. All of the gospel message rests on the authority of the Scriptures. In spiritual warfare, all we have is the truth and dependability of Scripture for our weapons and for our defence. If the devil can undermine that foundation by convincing believers that what they believe in is unreliable, then he has a much easier job dealing with them spiritually. The Christian is neutralised as a threat and rendered ineffective entirely.
