It should give Christians peace and joy to know that this faith is a faith proven through historical inquiry, reasoning, and logic. Above all, it is proven by the love and grace of God through Jesus Christ, who gives us the Holy Spirit.
The process of sanctification is God’s continuous work in our lives that produces a more clear image of himself in us and through us. You can give the world a ‘glimpse’ of God’s beauty and image through the things you are passionate about and gifted at.
The scriptures reflect all God wants us to know about himself, and he has provided more than enough evidence for us to be confident his plan for the NT (as well as the whole Bible) has been carried out in full.
