Theodoret of Cyrus: Providence and Prayer

Rejoice always (v. 16), in poverty and infirmity, when cribbed, cabined and confined. Pray without ceasing (v.17): this is not something impossible; it is easy when dining to sing God's praises, and when on a journey to ask for divine help. In everything give thanks (v.18), not only in prosperity but also in problems; God in his munificence know what is best. After all, this is God's will in Christ Jesus for you; he could easily allay every storm, but he wants to procure our salvation through the tempest.
