How do you share Christ at work?

I've been thinking a lot and praying about how to be a light for Christ at work. It's important to me and I can't stop thinking about it because I know that Christ has called us to share Him with those who don't know Him. The Great Commission, right? Well, I have to admit that I'm not at all doing well at being obedient in this. It bothers me and I've been feeling convicted by the Holy Spirit on this for a while. So I sit and I think and I pray and I try to devise ways I can share my faith- I try to get direct answers from God on this. Sure I live a life that reflects Christ at work...I treat my co-workers well, listen to KTIS on my radio, bake cake or cookies to bring in for them, yet God is showing me that this is not enough. It's not enough to just be a "good person" because that doesn't separate me from a "good person" who doesn't have Christ. It's a cop-out for me to say "But I'm sharing Christ through my actions" because I realize this is futile if I don't share my faith. Actions without words are as empty as words without actions.

But this is hard for me because I think too much! I care too much about how what I say might hurt or make another person feel awkward. I think too much about how others might conclude that I think I'm better. And all this is a sin. I know it is! It's me not having faith, not seeing things from an eternal perspective, elevating my feelings and their feelings above Christ's command to "go to all the Nations." It's like I see where I need to be but I don't know how to get there...

Recently, God has been showing me that I need to be in His word and in prayer every day and Jason and I have made this commitment. God's been blessing us through this and I'm praying that in seeking after God my passion for Him will grow. When I'm truly passionate in my love for Him I won't be able to keep quiet about what's He's done for me and about who He's been in my life and He'll give me the boldness I need to share His truth. And this is my goal. I want to honor God with every area of my life and I know I haven't been honoring Him in this. Christ says that,

"If anyone is ashamed of me and my words in this adulturous and sinful generation, the Son of Man will be ashamed of him when he comes in his Father's glory with the holy angels."
-Mark 8:38

Tears fill my eyes at even the thought of Christ being ashamed of me in Heaven. Yet I know that it hurts Him even more knowing that I'm ashamed of Him here on earth- because it's not about me and my feelings, it's about people coming to Christ. I hate the word "ashamed," yet I know that if I'm too scared to share Him with others, I am ashamed of Him. Pray for me as I struggle through this. Pray that God empowers me to be a light and that I'm obedient and take steps to grow in this area...
