Romans 8:28 is "A soft pillow for a tired heart" - R. A. Torrey
The Promise: "And we know all things work together for good"
The People of the Promise: "them that love God...them who are the called according to His purpose"
The God of the Promise: "...God..."
For us to find this passage a soft pillow for the tired heart, the God of the promise must not be the god of natural religion. Natural man approves a religion in which man is doing what he will, while God is trying to do what He can.
The God of the promise is a Sovereign God who possesses unlimited power, else He would not be able to work all things together for good. The God of the promise is an immutable God who is not susceptible to change, else we could not know all things work together for good, but perhaps wonder whether He will change His mind. The God of the promise is a compassionate and benevolent God who has a genuine care for His people, else He would not be working good. The God of the promise is a determinate God who has a definitely settled purpose, else this could not be all working according to His purpose.
"And we know that all things work together for good to them that love God, to them who are the called according to His purpose."
"Ye fearful saints, fresh courage take;
The clouds ye so much dread
Are big with mercy and shall break
In blessings on your head.
His purposes will ripen fast,
Unfolding every hour;
The bud may have a bitter taste,
But sweet will be the flower." - William Cowper
