Good evening! My advice is simple, Pray, Pray Pray and desire to Have a Deeper walk with Christ Through His Word, Fasting, Praising, Fellowship, Thanksgiving, etc. Desire to Know Christ in a more intimate way and while doing so Pray for opportunities to Share the Complete Gospel. This is what stepping out in faith is all about. He will Sustain you and Empower you with His righteous Right Hand!!! Ask for boldness, courage and the Words to Say. Pray this tonight, like isaiah did, Here i am Lord, Send me!!!!! I'm nervous almost every time i share the Gospel, but every time i step out in Faith, Christ Fills my heart with Words to say. Don't let nerves keep you from sharing, the Flesh is what is stopping you from sharing the Gospel. That stupid, stubborn, no good Flesh! But you have the power of the Resurrection Living Within you! You have God's Holy Spirit Dwelling inside of you. He wants to use you to Glorify God's Son Jesus Christ. Let Him guide and direct you, Rely on Him, Trust Him, Depend on Him to do with you as He wills! Praying for you!!!!
P.s. Sharing the Complete Gospel allows us to fellowship with Jesus Christ in such an intimate way. 1 Cor. 3 says we are fellow laborers with God and His presence is deeply felt when we are Sharing the Glorious Gospel of Jesus Christ. It gets sweeter and sweet every time you share!
and remember, He doesn't call us to convert anyone (That's the Holy Spirit's Calling) He calls us to be faithful. Don't fear rejection, they are not rejecting you, they are rejecting Christ. Ask God for a burden in your heart for Lost souls. If you're not going to tell them about Christ, Where are they going to get their knowledge of Him from? The media? And lastly, what an amazing truth it is to know that you were a part of Christ's Work if someone received Eternal Life! God get's all the glory, and it feels amazing knowing that you were faithful to Him!
