There are two men in the New Testament that are named Ananias. The first Ananias, with his wife Sapphira, is a cautionary tale for all believers. Don't allow pride and praise to get in the way of doing right. If you lie to the Holy Spirit to get praise for yourself, He will cut you down. That's what He did to them.
But it's the second Ananias who is possibly more important, and yet, more unknown. That's because many see him as a supporting character.
Which he was.
And that's why he's important!
Everyone knows who Saul, later known as Paul is. He is the man who wrote two/thirds of the New Testament. He began his story persecuting Christians, or how they were called before he was saved, followers of The Way.
Saul sat back and watched the stoning of the first martyr. He agreed with the stoning. He was a good Jewish boy and these "Way" people were blaspheming his God. So, after the stoning, he began hunting them down and throwing them in prison. He dragged both men and women out of their houses to be tossed into jail. He was eager to kill God's people, according to Acts 9:1.
He asked the synagogue in Jerusalem, if he could go to Damascus and round up all the Way followers and drag them back to the holy city. He was going to take men and women and drag them back to Jerusalem, where they were going to rot in prison until the death penalty.
But, as everyone knows, on the way to Damascus, Jesus knocked him off his donkey and asked him why he was persecuting Him. But what we forget is that the story doesn't end there. When Saul picked himself up off the ground, he was blind.
His companions had to lead him into Damascus. They found a place and Saul started praying. He didn't eat, he didn't drink, he did nothing. He sat in a room and he prayed.
So where is Ananias?
Ananias lived in Damascus. I wonder if some Christians ran when they heard that Saul was coming. If there was a great fleeing from Damascus, give Ananias some props for staying.
The Lord spoke to Ananias. In a vision, the Lord said, and I'm going to break this down in segments:
"Go to Straight Street, to the house of Judas," (Acts 9:11). 
I love when God gives perfect directions. He basically tells Ananias that he's going to '9134 Straight Street'. I have no doubt that Ananias probably knows who Judas is. If he didn't, it would say "to the house of a man named Judas." But He just says, 'to the house of Judas'.
"When you get there, ask for a man named Saul from Tarsus. He is praying to me right now." 
Well, the beginning of this sentence probably struck fear in Ananias's heart. He knew who Saul of Tarsus was. Saul was the person killing Christians and dragging them off to prison. I can understand that. We all know how it feels when God tells us to go and talk to someone we fear. But the fact that Saul was praying to the Lord at that moment, it's interesting. I'm sure Ananias had no clue what that meant. Jews prayed to the Lord. I note that my Bible uses the term Lord, rather then anything else. Is that Lord Jesus? or is that Yahweh? Does it matter? Saul is praying, that's all Ananias needs to know.
"I have shown him a vision of a man named Ananias coming in and laying hands on him so that he can see again"
I'm sure Ananias is sitting here going, "Me, God? You showed him me?" But not only that, it's the fact that Saul can't see. So now Ananias is going, "Me? You want me to go to SAUL and pray for his sight?". I'm sure that's overwhelming.
But Ananias tells God that Saul is a bad person! That he has authority by the priests to arrest and kill all the people who call on Jesus's name. And that's part of the reason why I love Ananias. He doesn't question God, but he tells him that Saul isn't a good person. That by praying for Saul, he's putting the other believers in harm's way.
But our Father is a good father, and Jesus is a good Lord, and Ananias gets some reassurance.
"Go, for Saul is my chosen instrument to take my message to the Gentiles and to kings, as well as to the people of Israel. And I will show him how much he must suffer for my name's sake." 
And again, I'm sure Ananias is overwhelmed again. He is the one that is ordered to go and pray for God's chosen instrument? Self-doubt is kicking in. "Me? Are you sure?"
But Ananias goes.
This is where people need to know about Ananias. He presented the facts to God about Saul, telling him that he'd heard bad things about the man, but he only did that once. Once, and when God was finished talking, Ananias went. He went to Straight Street, he talked to Saul's companions who allowed him into the house. He found Saul, probably face down on the floor, praying tearfully. Saul was dirty from the road and three days of constant, non-moving prayer. He was probably a little unhealthy looking, considering he hadn't eaten or drank anything in three days. He was also no doubt prostrated on the ground, begging God to forgive him and to give him his sight back.
Ananias could've turned back. He could've not even gone in the first place. But he went, he laid his hands on Saul, and he prayed.
And Saul was healed, and baptized. He was baptized before he ate something.
This is where we as people have our problems. We don't listen enough to go. We argue. We tell God that that can't happen. That person will never be saved. No matter what, it won't happen so why even try?
God calls you to share the gospel with the cussing, tattooed, monster of a man at work? "Oh, he won't believe".
God calls you to pray with the woman at work who you know is sleeping with the boss? "Come on, God. She's not going to do that!"
These moments, the times we argue with God, God doesn't want to hear it. He wants you to do as he says. Because who are you to know that that person you refuse to help, could've been the next Paul. Or the next Billy Graham? Or the next TobyMac? Who are you to say that that person you can't see a hope for, isn't the person who prays for your grandson and brings him to Christ? Or is the person who goes out and brings the gospel to an entire tribe of pygmies in the middle of a rainforest that you can only get to by eight days travel on foot?
Obedience is better then sacrifice, but usually to obey, we have to sacrifice something. It might be our pride. Might be our comfort. Sometimes, it's even our life. But you know, this world, it's only temporary. Who cares what happens here? Who cares if no one likes you, or if you're being ridiculed? Eternity is so much longer, and do you want to know, when you get to heaven, and your life is being reviewed, that that person you wrote off as 'never going to happen'? That person's only chance was you. Now, his eternity is tortured, because you were afraid.
So don't be afraid. Listen and obey. Be an Ananias. God's got your back. So go.
