This message examines the mysterious, yet pivotal biblical figure known as the Angel of the Lord, conclusively affirming that this Being is none other than the pre-incarnate Christ who appears at critical moments in Israel's history to reveal God's plan, deliver instructions, make promises, and forcefully move events toward their fulfillment. God's people are encouraged to develop a broader and deeper understanding of the spirit world, living above-the-sun, engaging with the unseen eternal realm by perceiving spiritually. Some of the key biblical episodes in which the Angel of the Lord are recorded are Hagar's flight (Genesis 16), Isaac's near-sacrifice (Genesis 22), Moses's encounter with the burning bush (Exodus 3), and Joshua's encounter with the Commander of the Lord's army (Joshua 5), demonstrating the Angel of the Lord acting with divine authority, accepting worship, speaking in the first person of God, orchestrating the fulfillment of His sovereign will. In every one of these appearances, the Angel of the Lord reveals elements of God's character: holiness, omniscience, mercy, faithfulness, and justice, modeling God's personal involvement in the lives of His people. Like Joshua, God's chosen saints should not question whose side He is on, but whether we are on His side, submitting, obeying, and trusting Christ to lead us into His Kingdom, fighting our battles, and ensuring victory providing we remain faithful. Like Joshua, we must take off our sandals, submit to the Holy Commander, choosing His side, doing His will, and He will lead us into inheriting the kingdom of God.
