God gave him the strength to be a good leader. He always told God that he wasn't a good speaker but God told him to do what he had to do anyways. The people saw that he was led by God and I guess God told their hearts that Moses was the one to follow. The important thing is he obeyed God. Listened, loved, and obeyed God. One very important thing he did was free the Israelites from slavary, so that played a vert big part about being a strong leader. He was also a very wise person.
God appointed Moses as leader. He argued with God that he could not do the job, but God prevailed.
Here are the issues that Moses raised (ibid):
1) "Who am I, that I should speak to Pharaoh and lead the Israelites?" Moses was very humble (Numbers ch.12) and wasn't sure of his worthiness.
2) "What should I tell the Israelites that Your name is?" The Israelites will want a direct relationship with You, not through a prophet alone, and they'll want to know how to address You directly.
3) "They won't believe me." The Israelites do not accept every newcomer and innovation; they are loyal to tradition.
4) "I can't speak smoothly." Moses' lack of smooth speech-ability might seem to reflect poorly on God's mission.
5) "Please send someone (else)." Moses was sure that there must be more qualified people, such as his brother, who was older and a prophet too.
More about Moses:
Moses was an Israelite, a great-great grandson of Jacob. He was born 245 years after the death of Abraham. The time when Moses was born was when the Pharaoh had ordered his people to kill all Israelite male infants because he (Pharaoh) was afraid that the Israelites would become too strong for him (Exodus ch.1-2).
Moses' mother didn't want him to die. So she made a basket for him and put him in it to float in the Nile reeds. He was found by Pharaoh's daughter, who took pity on him (Exodus ch.2) and raised him as her own son.
Moses was forced to flee after killing a cruel Egyptian taskmaster, and went to Midian, where he wedded the daughter of Jethro.
He eventually achieved the highest level of prophecy (Deuteronomy ch.34) and was called upon by God (Exodus ch.3). He brought the Israelites out of Egyptian slavery (Exodus ch.12). He received the Torah from God (Exodus 24:12) and later recorded it in writing (Deuteronomy 31:24). He went up on Mount Sinai for 40 days and nights (Deuteronomy ch.9-10) and brought down the Two Stone Tablets with the Ten Commandments (Exodus 31:18). He brought the Israelites into the covenant with God (Exodus ch.19 and ch.24), and he oversaw the building of the Tabernacle (Exodus ch.35-40). He was the humblest of men and the greatest of prophets (Numbers ch.12).
Moses lead the Jews from Egyptian slavery and received the Torah from God on Mount Sinai. In Judaism Moses is the greatest of all prophets and all prophets after Moses just saw a small bit of what Moses himself saw.

Around 1393-1273 BCE
Joshua was the leader of the Israelites after the death of Moses. It was him that led them across the Jordan River into the promised land (Canaan.)
Moses led the Israelites OUT of Egypt. Joshua led them into the promised land (roughly where Israel is today).
On Mount Sinai in Egypt, God created a covenant with the people of Israel by speaking to Moses, their leader. This occurred in Genesis chapter 34:10-28.
There were many leaders in Israel, from Moses in Exodus to Zerubbabel in Zechariah 4.6 to 14 And finally, the main leader, the chief cornerstone, which the builders rejected, Jesus Christ our Lord and our God.
Moses never entered Israel. In fact, Moses never set foot in Israel at any time in his life, either before or after the Exodus.
Moses literally did nothing in Israel ... he never set foot in the 'promised land'.
Moses was the God-appointed leader of Israel at the time when they were led out of the slavery (and attempted genocide/infanticide) in Egypt, eventually to enter the land of Israel or Canaan. They were thus liberated by God, through the chief agency and leadership of Moses. See Exodus ch.1 through 12.
Aaron helped Moses.
Moses is the Hebrew leader who received the Ten Commandments from God on Mount Sinai according to the Bible.
Joshua was a military leader, and eventually became the successor to Moses as the leader of the Israelites. He played a key role in leading the Israelites into the Promised Land and overseeing the conquest of Canaan.
