[In Hebrews 7:7] we see the principle of blessing: that the greater blesses the lesser. To be greater or lesser is not mainly a matter of age. It is a matter of the measure of Christ. We are greater or lesser according to our measure of Christ.
Whether we are greater or lesser depends upon our measure of Christ. If you have more of Christ, you are greater. If you have less of Christ, you are lesser. If by having more of Christ we are greater than others, then we are qualified to bless them; for the greater always blesses the lesser. The reason for this is that the greater one has a larger measure of Christ to give to others. If you are greater than I, it means that you have a greater portion of Christ than I. If so, then you have something more of Christ to minister to me. To bless others means to minister Christ to them. Those who have just a small measure of Christ need the blessing of those who have a greater measure. We bless them with the very Christ in whom we participate and whom we enjoy. If we enjoy Christ more, then we have more of Christ to minister to others. This ministering of Christ is blessing. (Life-study of Genesis, msg. 95, by Witness Lee)
