"Time is precious because we only have a limited amount of it. Giving God some of our time, we are actually giving him part of our life that we will never get back on earth. However, The Lord promised that whatever He receives as a gift from us He returns multiple folds. This is very applicable to the quiet time of meditation that we devote to the Lord. We receive back that gift of time in eternity."
