This sermon explores the Israelites' transition from wilderness wandering to entering the Promised Land, emphasizing that God provides in every season—during judgment, preparation, and promise. The central theological point addresses the danger of forgetting God's provision and claiming credit for our own success. Through Joshua's encounter with the commander of the Lord's army (a pre-incarnate appearance of Christ), the sermon challenges believers to ask not "Is God on my side?" but rather "Am I on God's side?" The message calls for complete submission to God's Word and recognition that everything we have—our gifts, talents, possessions, and opportunities—comes from God's gracious hand, not our own efforts.
