Joshua 1:9 (New Living Translation)
9 This is my command—be strong and courageous! Do not be afraid or discouraged. For the Lord your God is with you wherever you go.”
Acts 18:9-10 (English Standard Version)
9And the Lord said to Paul one night in a vision, "Do not be afraid, but go on speaking and do not be silent, 10 for I am with you, and no one will attack you to harm you, for I have many in this city who are my people."
Once we have found eternal salvation by believing in Jesus Christ, it becomes necessary that we tell as many people as we can. Problem is though many of us feel like we are going it alone, when we take a step of faith and decide to serve God. Nothing could be further from the truth.
Those of us who do believe only do so because God has rescued us for His purposes (John 6:44). God draws everyone, but many harden their hearts to His call. That is why He uses the witness and example of simple men and woman to be His "hands and feet", causing those who may not have heeded God's call to be drawn to the living examples of Jesus. Sharing the truth in love while extended a helping hand is very difficult to resist.
God goes before you preparing the way, by preparing the ground(the hearts of people)before you, and He goes goes behind you protecting you while you are in His service. His call is for us to go and do, following the call that He has placed within your spirit. Once you are truly "saved" it is diffcult to ignore that call. Don't worry and don't fear stepping out,just GO, because God "has your back".
