“Man can only receive what he sees himself receiving.
The children of Israel were told that they could have all the land that they could see. This is true of every man. He has only the “land” within his own mental vision. Every great work, every big accomplishment, has been brought into manifestation(reality, come to pass) through holding to the vision, and often just before the big achievement, comes apparent failure and discouragement.
The children of Israel when they reached the “Promised Land,” were afraid to go in, for they said it was filled with giants who made them feel like grasshoppers. “And there we saw the giants and we were in our own sight as grasshoppers.” This seems to be every man’s experience.
However, the one who knows spiritual law(don’t let the terms confuse you and don’t jump and take the wrong conclusions from them. Think of the essence of the words, and not soley the forms or formulations used), is undisturbed by appearances, and rejoices while he is “yet in captivity.” That is, he holds to his vision and gives thanks that the end is accomplished, he has received.
Jesus Christ gave a wonderful example of this. He said to his disciples: “Say not you, that there are still four months until the harvest comes? But behold(see), I say onto you, lift up your eyes and look at the fields; for they are ripe already to harvest.” His clear vision pierced the “world of matter” and he saw clearly the fourth dimensional world(in the spirit, a higher law, a different truth), things as they really are, perfect and complete in Divine Mind(God’s eyes, God’s outlook). So man must ever hold the vision of his journey’s end….”
