Sometimes God may call you to share the Gospel and/or your story of Salvation with someone that doesn’t treat you nice or someone you do not know.  If God puts it in your heart to share, the outcome is not yours to worry with it is God’s.  If we waited to share only with people who thought they needed Jesus we may be waiting a long time.  It’s the Holy Spirit that convicts them of their need for a savior, God that draws them and Jesus that saves them.  Your part is only because it’s God’s plan to use us to spread the good news of Jesus Christ. You are planting a seed on ground that The Holy Spirit is tilling up. Someone else may have to water the seed down the road before it can grow to salvation or you may get to see the whole process.  Sometimes even the person flatly rejects what you are sharing or they may lash out in some way in retaliation.  But as it says in 1 Peter 4:14 as far as your obedience to follow God’s leading if rejection occurs the glory of God rest upon you and God is glorified!  So as I told the youth group, sharing your faith is a win-win situation.  Results are; the other person has a new life in Christ and/or God is very pleased with your obedience and He is glorified!
