When God first chose Moses, Moses wasn't especially happy. He came up with various excuses as to why God should choose someone else. But rather than grant Moses' request, God got rather angry. "No! I, the mighty God who created this universe, have chosen you to do this task." The only inch God gave Moses, forbidding him to take the mile we all seek, was to give Aaron to Moses as a mediator.
Often, we are a lot like Moses. As Christians, we have been given a message to spread to all men. You could even say we have been given a message to speak to Satan: Let God's people go. But we don't always do it. Like Moses, we make excuses to make God please send someone else. Unlike Moses, we don't have the benefit of a burning bush giving us direct instructions. No one is telling us "go to this individual" or "go to this place" or even "post this message on social media". But we are told this: cast down arguments and every high thing that exalts itself above the knowledge of God, bringing every thought into obedience to Christ (2 Corinthians 10:5). Always be ready to give answer to anyone who asks you the reason for the hope that you have in Christ, with meekness and fear (1 Peter 3:15-16). Make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit, teaching them to obey all that Jesus commanded (Matthew 28:16-20).
Just like Moses, we have a mission from God. Just like Moses, it's not optional. There is no one else on God's list: You were chosen for the job before time even began (Ephesians 2:10). Unfortunately, just like Moses, we are often faithless. We make excuses. I'm not a good speaker. They won't listen. They'll think I'm crazy. They'll be offended. They'll unfriend me. They'll hurt me. It's better to let people make their own minds up. We are afraid, just like Moses.
But let me tell you some other things about Moses. Moses went whether he liked it or not. Ever tried resisting God? It doesn't work. Even if you don't want to do Gospel work, you're going to. Moses was also somewhat faithless. For sure, he had a strong relationship with God. But he still feared the Israelites. When God commanded Moses to speak to the rock to make it spill out water, Moses took credit for it, saying "Hear now, you rebels! Must we bring water for you out of this rock?" and he struck the rock twice. This moment of faithlessness cost him dearly. He would never enter the promised land, instead dying on Mount Nebo, seeing it but never being able to enter. 40 years walking in the wilderness, yet Moses never got to see the fruit of that labor. Joshua, his successor, finished what Moses started.
Which is another important thing about Moses, or rather about God. Despite Moses' failures, God still achieved His own goal. He could have done it if Moses had never been born. He could have done it if Moses had died prematurely. He could have done it if Moses had flat out rejected God's orders and swore allegiance to Egypt. With or without Moses' "help", God's will would have been done. God didn't need Moses, he needed God. When we disobey God, God doesn't lose anything. God isn't hurt, or even hindered. As if man, the clump of cells that we are, could stand in the way of the almighty. It's like trying to stop a train by lying on the tracks. When we disobey God, He doesn't lose out. We do. We have a chance to be part of His glorious work, yet out of fear or sloth or pride, we refuse, and the result is we don't get to be a part of it. Like the story of the little red hen: You don't help bake the bread, the bread still gets made, but we don't get to eat it.
But here's the most important fact about Moses. He was forgiven. He never entered the promised land, but he did enter God's Kingdom. His sin was not strong enough to overcome God's mercy and grace. Neither is yours. You fail. You disobey. You may never get to see your version of the "promised land". Perhaps the greatest fruits of your labor will be harvested by another long after you have passed on. Perhaps the opposite is true. I can't be expected to know what God has in store for your life. But this much I know: If you love God, as Moses did, you too are forgiven, and will enter a Kingdom far greater than that which was promised to Abraham and his descendants. Play your part in building that Kingdom.
