“All of Scripture is full of promises, stays and supports for our trust, to instill trust in us, for God knows how mistrusting we are.
Abraham is an example of this strong faith in God (Gen. 15), as is Jesus when He sleeps in the midst of the storm (Matt. 8:24).
This trust is a moral relationship as well, an act of the greatest devotion; all mistrust, all reliance on creatures, even on princes (Ps. 146:3), on the strength of flesh (Jer. 17:5), on temporal things and goods, and all worrying (Matt. 6:25-34; Luke 12:26-34) are therefore condemned.
Similarly, all indifference, every instance of ‘little faith’ (Matt. 8:26; 14:31; Mark 16:14; Luke 8:13; 24:25; James 1:6), is also condemned because God cares for us (Phil. 4:6; 1 Peter 5:7).
In this regard, Holy Scripture is terribly radical: it removes everything that is unsteady and unstable in earth and heaven, every foundation and all possible support for trust that might be placed in creatures; instead it replaces all that with an eternal foundation, unshakable and solid– namely, God Himself, Christ, His Word.”
