1. The Shield of Faith by DN Hoets

Habbakuk ends with "He will make my feet like hind's feet and He will make me walk on my high hills."  In other words, faith can lead you to high places in God like a hind scaling the heights above. 
However, unbalanced faith will not lead you to high places in God. On the contrary it will lead you to shipwreck.

2. Moving the Mountain by DN Hoets

There are two pictures of moving mountains in the Scriptures. Often the picture in Zechariah 4 is overlooked. To be true to Scripture, we need to look at both accounts before forming any doctrinal emphasis. If we do not do this, our perception of the truth will be distorted and we transgress and lead others into error.
