Matthew 5:14 Ye are the light of the world. A city that is set on an hill cannot be hid. 15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. 16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
There is a labor we can do that will affect people for eternity. It is laboring in the work of the Lord and doing good works. You’ve probably heard the song, “This little light of mine, I’m gonna let it shine,” at some time in your life. The Bible calls us the light of the world. We are exhorted to let our light shine before men. This is a must during the Last Days and perilous times where darkness is covering the Earth and gross darkness its people. The shine of our light inside of us is the good works we do outwardly. The OT prophet Isaiah said our light shining would cause unsaved people to come to our light which can lead to them opening their hearts to the Gospel, “Arise, shine; for thy light is come, and the glory of the Lord is risen upon thee. 2 For, behold, the darkness shall cover the earth, and gross darkness the people: but the Lord shall arise upon thee, and his glory shall be seen upon thee. 3 And the Gentiles shall come to thy light, and kings to the brightness of thy rising Isaiah 60:1-3.”
Men cannot see that we are changed people, saved, and new creations in Christ. They cannot see our faith but they can see an outward evidence of our inward change when they behold our good works. Our good works witness. First Peter 2:12 says, “Having your conversation honest among the Gentiles: that, whereas they speak against you as evildoers, they may by your good works, which they shall behold, glorify God in the day of visitation.”
It is not natural to do good works for God it is supernatural. Our good works come from our walk with Him and they begin at the Cross. After we come to Jesus’ work on the Cross and get saved we are from that point onward to get our walk outwardly to measure up to His work inside us. This is called working out your own salvation (Philippians 2:12). God worked it in (inside our new creation spirit) now we work it out (in our walk and works). It should be seen by our behavior and good works we do. It will impact eternity.
