Samuel turned the age in God’s administration from the age of the priesthood to the age of the prophethood with the kingship. This was a great thing not only in the history of Israel but even in the history of mankind. Moses was a priest, and after him God’s administration was centered on the priesthood (see note Num. 27:211a). The priesthood was to minister the word of God to His people and to exercise the authority of God over His people. The Aaronic priesthood failed God in these two things. At the waning of the God-ordained priesthood, God began a new age in raising up Samuel, a young Nazarite, as a faithful priest to replace the waning priesthood (1 Sam. 2:35). God ministered His word to His elect by establishing Samuel as a prophet in the uplifted prophethood (3:20-21), and He exercised His authority over His elect by raising up Samuel as a judge (1 Sam. 7:15-17). Samuel, as the last judge, terminated the judgeship, and, as the new priest, brought in the kingship, which was strengthened by the uplifted prophethood, in which Samuel was established as the first prophet (Acts 3:24; 13:20; Heb. 11:32). Through Samuel God set up a governmental administration in His economy so that He could fulfill His promises to all the forefathers and accomplish His desire according to His economy, that is, to have a line of genealogy to bring Christ to the earth.
At the end of his ministry, by the time that Saul was raised up to be the king in Israel (1 Sam. 9:3-27; 10:1-27), Samuel had reached the highest position, only God being above him. Thus, as God’s representative, Samuel was the acting God. However, God did not have any intention to make a kingdom of Samuel. Rather, God determined to raise up David, through whom He intended to build up a kingdom (2 Sam. 7:12-13). God had the intention that Christ would be born in the lineage of David. Hence, God raised up Samuel and prepared him for His use to do whatever was necessary to gain, through David, the proper genealogy of Christ. As a Nazarite according to his mother’s vow, Samuel had no heart for anything other than God and His elect. He could be used by God to carry out His economy because he was a man according to God and God’s heart, having no self-seeking nor any thought of self-gain.
