Making an Impact

I feel that recently God has really laid it on my heart to make an impact to the area around me, and that doesnt mean that im going to get fat. Ok, so enough with the humor, if it was humorous as most of my jokes arent. But in all seriousness, i feel like im not being enough of an influence to fellow Christians and to non-Christians alike. I want to be more outgoing about Christ and more of an encouragement in my faith in Christ and really set example for all who are around me, especially the younger generation. But unfortunately ive wasted so many opportunities to share Christ and what He's done for me in my life. I know that God has blessed me with an amazing testimony thats unique to me and that can really change lives if God wants that to happen, but im too shy to share it sometimes and i know thats wrong. Im trying to make the right moves when i step out to share my faith but i dont feel like im succeeding because im a failure at it so many times. Thankfully it is by grace i haved been saved and not by works so i can boast. Recently i shared my testimony at my schools FCA (fellowship of Christian athletes) and i honestly dont know how many peoples lives i affected. I know a few people said that it was encouraging and that was a blessing to me. And in a few weeks im sharing the gospel at a bonfire my youth group is having. But i feel like thats not enough. I know God can do major things through me but im always preventing Him from working because of my stubbornness and laziness and having too big of an ego, even though i should have no boast except that of which is in the cross. All in all im just struggling with being an impact for God and really living up to all that God made me to be. My daily walk has been better and im hoping that will help me reach out to others more. i want to ask for prayer in being bold and growing a passion for the Lord and for advancing His kingdom. Another thing im struggling with personally, and yes i know im kind of venting now and i apologize but bear with me, is what God's plans are for me in the here and now. Whether it be about getting a job, girl situations, or just my daily walk and where i plan on going with it and where i want it to reach and so on. the list is ever long. i just need prayer for that as well. sorry for the venting, i just needed to get it out and also ask for prayer on it as well. Thanks for bearing with me!
