God does not. Neither does Christ, Hebrews 13:8.
The next thing I noticed was some of the parallel words and phrases, cultivate (Psalm 37:3) commit (Psalm 37:5), with all your heart (Proverbs 3:5), acknowledge (Proverbs 3:6). The picture emerging was one of a sustained practice of trust. Trust is not presented as a quick fix. Not something we pull out of the tool bag when things are difficult. It is a sustained life choice. It is the bedrock of our lives.
Third, as I worked through this it was crystal clear, to me at least, that without God’s intervention in my life I simply would not trust Him. He chose to reveal Himself through His Word. He chose to send His Son. His Son chose to die for me and give me life, Romans 6:8 and Colossians 3:1 - 4. He sent His Spirit to indwell and empower me. Without that – no trust.
It is because of who He is, what He has done, and His work in my life I am able to trust.
