Moses Is Dead

Deuteronomy 34:5-8
"So Moses the servant of the LORD died there in the land of Moab, according to the word of the LORD. And he buried him in a valley in the land of Moab, over against Beth-pe'-or: but no man knoweth of his sepulchre unto this day. And Moses was an hundred and twenty years old when he died: his eye was not dim, nor his natural force abated. And the children of Israel wept for Moses in the plains of Moab thirty days: so the days of weeping and mourning for Moses were ended."

Moses' time had ended. He had completed his journey and purpose in life. It was now time for someone else, whom God appointed, to lead the Israelites.
Moses had done many great signs and wonders by God. He threw down his staff where it became a snake, and he placed his hand in his bosom and it became leprous. Moses led the children of Israel through the Red Sea as God parted and held back the waters while they crossed. Moses did many other things with the annointing and power of God.
In the particular scriptures given above, Moses' time had come to an end. Although, the children of Israel had followed Moses the entire time they wondered in the wilderness, they were now faced with something new.
Moses who had been an exceptional leader, chosen for the Israelites by God, was now dead. I imagine that in the 30 days of weeping and mourning that the children of Israel felt like giving up perhaps or maybe they were scared. Here they were weeping and mourning for the man who had faithfully led them through some very hard times in their lives. Moses was like a security blanket and now he was gone.
We, too, sometimes in life get "attached" or used to something. We like things because we are familiar with them. And then we get scared or pout because things aren't the way they were.
God used Moses to lead, guide, and help the children of Israel. Moses had served his purpose. God was about to do a new thing for the children of Israel. God had plans for the Israelites to help them and prosper them. But if the children of Israel would not have "moved on" from Moses' death, God could not move them forward to the promised land.
There are a lot of us out there who will not quit mourning for Moses. Our Moses could be past relationships, jobs, friends, habits, or anything else we use as a blanket of security that God has taken away. When God gets us out of certain relationships, there is a reason for it. When God does not allow us to do something we have always done, there is a reason for it. And not all of our "Moses" have to be bad things. We could be used to a certain way of praise and worship or prayer.
When we are encountered with any change in our "normal" everyday life, we are allowed to go through a grieving process. The children of Israel grived for Moses 30 days. But then they ended their mourning.
If we are serving the Lord and walking uprightly before Him then He is leading and guiding us. And when the Lord leads us and guides us, it may be a little scary to experience the unknown. But we have to step out in faith, knowing God's plans are to prosper us and not to harm us. And that everything that we go through, even though it may seem difficult at the time, there is a reason. And when God makes us get out of situations by taking people or things from our lives it is because He has better plans for us. So when He gets rid of whatever "it" is then we need not to continue mourning or grumbling over what was lost, knowing God is fixing to do something.
So BURY your Moses. Then GRIEVE over your Moses (if necessary). And then ARISE!
Joshua 1:2 "Moses my servant is dead; now therefore arise, go over this Jordan, thou, and all this people, unto the land which I do give to them, even to the children of Israel."

We should also know that no matter what the Lord takes away, gives, leads us to or from, He will always go before us to get us through it. He is always there.
Joshua 1:9 "Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the LORD thy God is with thee withersoever thou goest."

So we need to let go of the past. The past and hanging on to it will keep us from our futures that God has in store for us.

Isaiah 43:18-19 "Remember ye not the former things, neither consider the things of old. Behold, I will do a new thing; now it shall spring forth; shall ye not know it? I will even make a way in the wilderness, and rivers in the desert.
