"...in addition to all, taking up the shield of faith with which you will be able to extinguish all the flaming arrows of the evil one." (Ephesians 6:15)
It’s imperative that we understand and know what are we are placing our faith in. Faith requires a large dose of trust. As with anything of importance, examining the evidence is a must. In terms of our belief and reliance on God of the Bible, we can see from Scripture that God is faithful and unchangeable, and that we can trust Him to fulfill all His promises to us.
