Look, I am ready this third time to come and visit you; and I will not be a burden to you; for it is not what you own that I want, but you! Children are not supposed to save up for their parents, but parents for their children. And as for me, I will most gladly spend everything I have and be spent myself too for your sakes. If I love you more, am I to be loved less? Complete Jewish Bible
Neither the end of the story of the Church being built up in love, nor the end of the story of the Kingdom of Jesus coming to earth from Heaven are going to be written by us. We may be in the last chapter somehow at this time, but there are others who need to be equipped to bring forth their contributions and release their revelations of what Heaven wants to impact the earth with.
No cost will be to great to invest in those who are brought to us by the Spirit to raise up into their destinies. Even the least of them will be greater than John, who baptized Jesus, who was the greatest prophet ever born (Luke 7:28).
