Because those who don't stand out are servants with limitations. They have boundaries which block God's power in them. They're not always willing when God needs to use them, like in very simple situations.They fail to see that because of their boundaries and their "own will" they're unable to... Why? Because their "own will" overpowers them.
During the time I wasn't able to do anything, while I was recovering from an incident, I saw and learned a lot more about this. I asked myself every day, am I a servant with limitations? Where can I serve more? Where does God want more of me? Do you know why I kept asking this? Because I saw many people who were servants with limitations, and the worst part is that they had not even noticed it, I have prayed to God not to be that way, because there's a chance, I haven't seen it as well, but I want to... I want to be a limitless servant for Him.
How can one be a limitless servant? Is it with the strength of your arms? Or is it to do so much and later on, lose your physical strength and start complaining? Is it being part of everything, always being in charge, and putting down others who follow you? Not at all friends. God works quite differently than you can imagine, if we don't understand that, God will not have the freedom to use us.
He tests us all the time, to see if what we say in our prayers is indeed true, "Lord, I am here! Use me!" to see if you're being sincere. And how does He find out? In the simplest situations in our day to day, and once he approves us, He is able to do through us what He needs.
Here are some situations He has shown me:
Be sympathetic with the people that go to church, but don't want anything to do with God, you know those who only go to waste time? (God showed me that if they're still going, it's because He wants to save them, and I need to be in God's plans in order for Him to work in these people.)
Serve those who currently have limitations (Even if they think I'm a fool because I'm always trying to serve them, even if they may take advantage of me, with my attitude God will eventually show them that I'm doing the right thing, that I'm serving God. I'm not worried about who I'll have to serve).
Doing things only for the eyes of God (No one is watching me and, I don't tell anyone when I clean the church restrooms but, God is being glorified when people go in and say, "This restroom smells nice, I wondered who cleaned it..." I don't even need to say it was me...
Or, arriving earlier to the kids zone, anointing the class and making a prayer... Or, to stop ironing on my ironing day and accompanying with joy a friend who needs to go to the doctor... Or, when I go grocery shopping for myself and remember an item that we need for the kids zone and buying it, even if it's something small... Are you getting it? We can be an a servant without limitations at every moment.
The servant without limits doesn't THINK at every moment about the Work of God, like they have to clock in and only serve during this time and, when it's time to clock out, they forget about this and go about their life, with their desires thinking it's "their time". The servant without limits lives THINKING at every moment about the Work of God, they may already be doing something for God but are still thinking what else they can he do for Him. They don't have limits... this is what makes the difference!
Where can I go from Your Spirit? Or where can I flee from Your presence?
If I ascend into heaven, You are there; If I make my bed in hell, behold, You are there.
If I take the wings of the morning, And dwell in the uttermost parts of the sea,
Even there Your hand shall lead me, And Your right hand shall hold me.
