The answer is: Joshua

Joshua 1:1-2 - After Moses' death, God commissioned Joshua to lead Israel into the Promised Land. This transition highlights continuity in leadership and faith. Interestingly, the name "Joshua" means "Yahweh is salvation," which connects to Jesus—often called the new Joshua—for leading believers into a greater promised land of salvation (Matthew 1:21).

The transition from Moses to Joshua is one of the most pivotal moments in Israel's history. It speaks volumes about God's faithfulness in unresolved challenges. After leading the people through the wilderness for forty long years, Moses' passing heralded the new opportunity that awaited with Joshua. It’s fascinating to note that ancient Christians often viewed Joshua as a foreshadowing of Jesus, not only because their names mean similar things but also due to their roles in guiding their communities towards salvation and promise.

Joshua's faith and strength are explicitly underscored in God’s commission in Joshua 1, where God reassures him to be "strong and courageous." This refrain not only serves to bolster Joshua at a fraught moment but echoes throughout Scripture as a reminder to all believers of the strength they can harness by faith.

Furthermore, Israel’s crossing of the Jordan River under Joshua mirrors the previous crossing of the Red Sea—highlighting themes of miraculous change and divine presence in huge life events. The story of Jericho, where a telltale shout and the fall of walls mark victories not just due to physical might, but spiritual obedience, further emphasizes that this journey isn’t just territorial—it’s a journey toward a deeper communion with God.

In every iteration of mentorship and new beginnings, there's a beautiful symbolism about beginnings being infused with divine hope. As, of course, every ending leads us to learned beginnings—much like Joshua's new stint ushering the pliable Israelites onto their next chapter.
