Speak truth~ Speak life! "Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen." Ephesians 4:29
Being salt and light means speaking truth and speaking life. It is so easy to get caught up in political discussions today as most is anti-Christ. If you want to change the heart of someone and get them to embrace their Savior Jesus Christ as You have embraced Him as yours then speak truth, speak life.
That means when you find yourself up against the opposition then try to move them toward Christ and not away. It is not easy to do. It requires you to have a strong heart for Christ and know that His will is to have all His creation be saved.
I heard a good story about a person who was faced with the opposition - Satan. This person met another person who was a professed atheist and was degrading Christians and calling them the problem with the world and that Christians are the real 'haters'. The person who told this story said that it was hard for them to stand in front of this person and look them in the eyes while they spewed his atheist vulgar righteousness. In a moment, the person taking in all this profanity realized that this guy was in trouble. What he wanted was out of the tangles of a world that offers no hope, he wanted to be set free...
So, once he finally got to say something, he said " Hey man, I know where you are comin from. But I just want to tell you that we may be in this world but we don't have to of it. We don't have to feel condemned, and unforgiven, we don't have to worry about not being loved because Jesus Christ is alive and He loves us, He loves you! He gave His life for you so that you can live with Him forever. He knows the pain of your sins and forgives you. Accept that forgiveness and His love and You will be free indeed." John 8:32-38
