For so hath the Lord commanded us, saying, I have set thee to be a light of the Gentiles, that thou shouldest be for salvation unto the ends of the earth.
Acts 13:47 KJV
If you’re driving at night, when there is no moon, you had better have working head lights. Otherwise you’ll not be able to see where you’re going. You may run into something and hurt yourself or someone else.
Going through life without Jesus is like driving in the dark. Jesus is the light of the world.
If you are already a Christian then you are now the light of the world. It is now your job to illuminate the path of the lost so that they can find their way home into the arms of God.
But how will people call on Him in whom they have not believed? And how will they believe in Him of whom they have not heard? And how will they hear without a preacher (messenger)? ROMANS 10:14 AMP
Be a messenger. Tell everyone you can about the good news. Jesus saves, heals and delivers.
