I went to Wal-Mart tonight to do my shockwave challenge. After grabbing a Christmas present for Karis (I couldn't resist) I was walking out to my car and saw two cart pushers standing around talking. I approached them and invited them to church. I asked them the million dollar question and one of them said he hoped he would go to heaven and the other said he knew for sure. After I shared the gospel with them, I found out that both of them had already confessed Jesus as Lord. I prayed with them about their job and encouraged them to not let the mistakes they make discourage them from being secure in their salvation.
Don't forget about the challenge! Get out there and share your faith!
