The world is driven by self-preservation and self-promotion. Individually, the natural man is guided by self-serving motives. This should not be true of saints.
It is always right to do right, but it is more perfectly right to do right for the right reasons. In other words, serve the Lord, but do so out of a pure motive.
One must choose his reward for actions taken. Would he rather receive eternal reward from God the Father, or temporary praise and recognition from his peers?
How would making your motive match the Lord's motive change how you approach the Christian life (from witnessing to praying to Bible reading and so on)?
Thankfulness strengthens and builds one's faith in the Lord. Christians need more outward and vocal expression of their thankfulness for God's provisions and blessings. Giving of thanks simply exalts the Lord. According to scripture, man can “magnify him [God] with thanksgiving.” Something magnified is made easier to see. Therefore, when men give thanks to the Lord, they make God more visible to a world overcome by sin. For what do you have to be thankful? Try giving God thanks for answered prayers, deliverance from trials, or simply His daily provisions. This thankfulness would help the world to see Him better. Ungrateful Christians have helped to convince the world that it does not need to give God credit for creation (and redemption among other things). Long before these perversions of truth, Christians ceased to give thanks.
