John the Baptist prepares the way for Jesus - Luke 3:7-14 (also in Matthew 3:7-10)
John's message demanded at least 3 specific responses.
1 - Share what you have with those that need it
2 - Whatever your job is, do it well and with fairness
3 - Be content with what you are earning
John had no time to address comforting messages to those that lived careless or selfish lives - he was calling the people to right living. Just as a fruit tree is expected to bear fruit, God's people should produce a crop of good works.
God has no use for people that call themselves Christians but do nothing about it. Like many people in John's day who were God's people in name only, we are of no value of we are Christians in name only.
If others can't see our faith in the way that we treat them, we may not be God's people at all.
That is one lesson that i wish i had read a long time ago. I have always called myself a Christian. I remember Danny and i arguing about this all of the time. Well he did anyway. I never saw the point, in arguing with him about anything in the end. I would just get screamed at and abused...but i have, in the past, been very guilty of what this lesson talks about.
