I don't remember the name of the pastor, but a new Christian once asked him about how to deal with having lost friends and the pastor told him not to worry about it. The pastor told the young man if he was living for Christ his lost friends would soon not want to be around him.
When the young man, who had been saved while away in the military, returned to his home and his lost friends showed up he found out just how right that pastor was. His lost friends didn't want to hear about his Saviour and Lord, they didn't want to hear the Gospel, they didn't want to hear about his life with Christ, and since he was no longer willing to do the sinful things they all used to do for fun, his lost friends were soon nowhere to be found.
One who is truly following Christ can't help but shine the light of Christ for others to see. They can't help but talk about their Saviour and Lord, they can't help but want to try and help those around them know Jesus, they can't help but share with them they are about to crash and need to change course.
If one wants to hide their Christianity, if one wants to keep silent about Jesus and doesn't care enough about the lost folks around them to warn them of danger, and if a professing Christian is willing to hang out with the lost and act much like them, then sure, they may have several lost friends.
Those who do this should pay heed to Scripture and make their calling and election sure. Then they should look to Scripture and be reminded that worldly friendliness isn't love; that true love is sharing the Saviour with the lost and warning them of the dreadful fate of being without Christ.
Our words, actions and lives are to be lived in such a way as to example Christ, drawing the lost to salvation and warning them of the danger they are in.
TODAY is the day of salvation. None of us knows when our time will be up. We don't know if ourselves or a lost person we know may die tonight; or if Christ may return before we meet again. Dare we delay in sharing Christ with the lost? Dare we put off warning the lost of what awaits them if they remain lost?
