Have you ever tried to use an appliance or piece of equipment and it didn't work? I remember my frustration about two years ago when my almost brand new TV suddenly stopped working. I tried everything including banging it with my hands to no avail. The expensive top of the range TV had ceased to do it's job.
That means wherever we go, whatever we are doing, as Believers we have to be changing the environment around us just like the salt changes the food its added to. Our environment should be better because of us. If we are not affecting the world around us that means that we have lost our purpose and as Jesus says, "...that salt is good for nothing but to be thrown out..." Matthew 5:13 We will become like the TV I bought which stopped working and had to be thrown away.
How then do we enhance our environment? What are we supposed to be doing to add our saltiness to the Earth?
I believe that we are supposed to first of all demonstrate our love for God by loving other people. This can be through doing good for others whenever we get the chance, a helping hand here and there, a prayer for someone, a word of encouragement and so on.
Thirdly I believe that we can enhance our environment by sharing the gospel with unbelievers, we will ultimately play a role in changing their lives and henceforth change our environment. So when was the last time you witnessed to someone and told them about God's love or Christ's work on the cross?
Don't kick yourself if you haven't done so in a while. Dust yourself up and get going. There's many out there who are looking for answers and the good news is, we have the answer. Lets spread the love and share the message of the Cross with all.
