We are all called to be have the mission of sharing the gospel and making disciples.
Matthew 28 19 Therefore go and make disciples of all nations, baptizing them ina the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.
One of my favorite songs growing up was "Be a missionary every day! Tell the world that Jesus is the way! Be it in the town or country, or busy avenue. Africa or Asia, the choice is up to you! So be a missionary every day! Tell the world that Jesus is the way! The Lord is soon returning, there is no time to lose, so be a missionary, God's own emissary! Be a missionary today!
But missions is hard work. It takes careful preparation of your mind with scripture and clear application of it, your heart in learning to depend on and list to the Holy Spirit, prayer in God guide you to the mission field he is calling you to, and often other skills that enhance your ability to be the hands and feet of Jesus to others.
Having partnerships with other's sharing your calling and mission field is also important for a base of prayer, emotional, and when in full time missions, financial support.
