The heart is central to the Christian faith

[Waylon]

The “heart” is here put for our whole inner being, the “hidden man of the heart” (1st Peter 3:4). It is that which controls and gives character to all that we do, and say. To “keep”~garrison or guard~the heart or soul is the great work which God has assigned us: the enablement is His, but the duty is ours.

Whether we fully understand it or not, God is sovereign over the events in our lives. No matter how bad the crisis may appear to be, it is never beyond His ability to resolve it. Every crisis in our lives is part of God’s sovereign purpose for us. We may not understand that purpose while we are going through the struggle, but we will eventually see how the circumstance was for our benefit.
