Fellow Believer: What’s your favorite part of the Bible?
Me: I like all of it.
Fellow Believer: No, but what’s your favorite Scripture?
Me: I like all of it.
Fellow Believer: I know, but what verse in the Bible do you like most?
Me: I like all of it because I use specific parts for specific things; some for healing, others for financial issues, some for protection, others for peace, some for prayer given by the Holy Spirit, and others to build confidence even as I cast down doubt & fear, in Jesus’ name.

Essentially, why limit oneself to part or some of God’s WORD when He has given us all of His WORD? In regard to faith that both pleases God and by which the promises of God manifest in our daily lives, the most powerful is Mark 11:23-24.
