Missionary zeal does not grow ...

Missionary zeal does not grow out of intellectual beliefs, nor out of theological arguments, but out of love. If I do not love a person I am not moved to help him by proofs that he is in need; if I do love him, I wait for no proof of a special need to urge me to help him.

Missionary zeal does not grow out of intellectual beliefs, nor out of theological arguments, but out of love.

The apostles were moved, not so much by an intellectual apprehension, as by a spiritual illumination. They met men, and the need of those men whom they met cried aloud to them.

In arriving at a decision in a question of doubt, the apostles in the Acts were guided solely by their sense of the Spirit behind the action, not by any speculations as to consequences which might ensue. And so they found the truth.
