Jesus can make those happy who trust him and call him, whatever be their outward condition. He can give them peace of heart in a prison, contentment in the midst of poverty, comfort in the midst of bereavements, joy on the brink of the grave. There is a mighty fullness that is ready to be poured out on
every one that will ask in prayer. Oh that people would understand that happiness does not depend on outward circumstances, but on the state of the heart.
