And we intuitively know that all things work together for good to those who love God, to those who are called according to purpose (Romans 8:28).
We love God by loving the brethren (1 John 4:20). When we are loving Him, all things will work out for our benefit. This is not referring to financial benefit, but to maturity in spiritual things. This type of love seeks the best for the one loved and is an aspect of the fruit of the Spirit. Thus, we must be spiritual—governing our lives by the desires from the Spirit—in order to love other saints in a proper manner, and thereby love God.
