“Faith in the biblical sense is substantive, based on the knowledge that the One in whom that faith is placed has proven that He is worthy of that trust. In its essence, faith is a confidence in the person of Jesus Christ and in His power, so that even when His power does not serve my end, my confidence in Him remains because of who He is.” - Ravi Zacharias
This we know, but I am mildly held from this comment. If its “substantive” you want (and we do), then take away all props to build upon, so that faith won’t be confused. Reduce the subject to the Master’s identifying: “Oh you of little faith”, to bring forth His jewel for use, to bless and to grow. Indeed, some things are for our edification, exhortation, keeping, but faith must be consecrated. I’m not saying to isolate it from the exuberant expression of all the proclamations of the Almighty. But somewhere in the fray in some corner of the world is a building of the “faith” He said He would find upon His returning. It may not have the advantages of the above, but the below. What kind of “faith” would it take to wield the Lord Christ’s praise of honor? The kind coming from your brother or sister whom acts upon it as if it were his/her own table to eat at, though it is God’s, his own tool to work with, but that too has been supplied, upon which God gives the increase from the very smallest steps of faith.
