Philippians 2:18

Do ye joy... — The Epistle lays great stress on joy, not only as a privilege, but as a duty, following from Christian faith and proving its reality. Joy is in itself natural in the first thoughts of childhood and youth; it is apt to be chequered or even destroyed by the second thoughts of fuller experience of life, as darkened by suffering, sin, and death; but in the third and deepest thoughts of the Christian, recognising these darker elements of life, but knowing that they were not in the beginning, and shall not be in the end, joy comes back, solemnised but deepened into thankfulness. A Christianity which has no power to rejoice, either in flashes of joy amidst tribulation, or, better still, in the calm steady light of cheerfulness, may be true, but is imperfect. It has not yet entered into the promise given by our Lord Himself of the “joy which no man taketh from us” (John 16:22).
