in hope of recompense

In the Sermon on the Mount about all God-pleasing deeds—prayer, fasting, and alms—the Lord commanded to do them secretly. Why? Because the Heavenly Father will reward you openly. Therefore, a Christian should prepare future bliss for himself through all his labours in life; he should build himself an eternal home, and send provisions there in advance for all eternity. This is not being mercenary, because one’s own material interests as such are limited to this life, while [the future] life is to detriment of these interests. Furthermore, it is impossible to live this way without faith, hope and love towards the Lord. Acting according to the commandments in hope of recompense is also an abstract action. And yet it is closer and more distinct for the heart than anything else which is too unreal, as for example to do good for the sake of good. You will not find the latter anywhere in Scriptures. The higher incentive is here: do everything for the sake of the Lord and do not fear loss.
