Romans 8:28
And we know that in all things God works for the good of those who love him, who have been called according to his purpose. — The συνεργέω (synergéō, "work together") of πάντα (panta, "all things") toward τὸ ἀγαθόν (to agathon, "the good") is the confidence of those who ἀγαπάω (agapaō, "love") God and are κλητοί (klētoi, "called") κατὰ πρόθεσις (kata prothesis, "according to purpose"). This is not promise of ease but assurance of divine superintendence. All things—suffering, waiting, groaning—serve the good of the beloved.
