Many people who claim to be Christians are not pastors or teachers or serving overseas as missionaries. They are just members of their respective churches. But…we are called to be ambassadors for Jesus Christ wherever we may be. At work, at home, at school, at the mall or at a restaurant eating out, if someone sees you blessing your food or any other action which might identify you as a Christian, then you should represent Christ in whatever capacity you can.
When we are called by God’s Holy Spirit to repent of our old ways and follow Jesus, we are also called into His ministry. This is not optional, it’s just part of being a follower of Jesus. The disciples knew it and everyone who knew them also knew that they were His followers. It is a ministry which doesn’t have a retirement date until you meet Him upon your death.
Does Jesus require us to do this for our salvation? No, it is not a requirement because He did all that was needed for you to be saved. It is up to you to accept the gift of salvation and atonement from Him when you feel the need for giving your life to Him. The Holy Spirit convicts you of your need but it is your responsibility to accept it and ask Him to come into your heart and change you into the person that He knows you can be. His ambassador wherever you go or whatever you do. That is your calling after you have accepted Him and truly given your life over to Him.
Salvation is not a sometimes thing and it isn’t something that you can choose to use when you need a blessing from God and then turn it off. True salvation is a change in your heart and soul because you KNOW that you need Him to change you into that person that He already knew about but you didn’t want to until the Holy Spirit convicted your Spirit of it through faith and by your accepting His Grace for your new life in Him. We are not born into the family of God, we are invited to join by God’s Spirit which convicts us of our need for Him.
Eternity is waiting for each of us and there are two different places where we will spend it. Heaven for those who give their lives and their hearts to Jesus and live a life of service and grace through faith in Him. The hell of separation from God’s Presence with the demons and Satan because you refused His grace and the salvation that only He can bring into your life. When we hear a message about salvation at church or a revival meeting and we don’t know Jesus yet, it is our responsibility to either accept it as the wonderful gift that it is or to reject it and go about our life as if we have all the time in the world. But nobody has that luxury.
