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)?
Paul and Barnabas admonished the heathen to turn from “vanities unto the living God.” One cannot trust in the Lord and simultaneously trust in anything else. In order for an individual to be saved, he must repent of trusting in anything other than the Lord. One aspect of repentance involves ceasing to trust vanity and turning one’s faith toward the living and true God. This saving faith needs to become a living faith following salvation. Believers should consistently turn from “vain thoughts” and love the law of God (Psalm 119:113). They should turn from the vain labours that spend their strength for nought (Isaiah 49:4) and be “steadfast . . . in the work of the Lord” knowing that their “labour is not in vain in the Lord” (1 Corinthians 15:58). Additionally, believers should turn from “vain words” (Ephesians 5:6) and hold “forth the word of life” (Philippians 2:16).
The book of Ecclesiastes contains documentation of Solomon’s life experiment apart from God. He examined the worth of subjects involving happiness, wealth, labour, and death. Ultimately, he concluded that life “under the sun” (Ecclesiastes 1:14) was vanity. The word vanity means empty or meaningless. Though Solomon wrote extensively concerning vanity, he was not the only person in the Bible to declare the vanity of life. In fact, Solomon’s father David declared that “every man at his best state is altogether vanity” (Psalm 39:5). King David added that if both men of high and low degree were laid in a balance together, they would be “lighter than vanity” (Psalm 62:9). Thus, regardless of worldly accomplishments and accolades, a life void of God remains meaningless.
