God calls people into different works. In the midst of this diversity, a common thread unites all the work—men ought to do all they do to the glory of God.
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)?
The believer’s every endeavour should be done for the Lord and not simply for men. All should be done to the glory of God even to the extent of what man eats and drinks (1 Corinthians 10:31). Before the believer considers changing appearance for the sake of beauty, he or she should ask whether or not this thing will bring glory to God. Before a believer marks his flesh with a tattoo, he should consider the words of His God (Leviticus 19:28). Before spending a great deal of money on one’s appearance, he should ask if God would rather the money be given elsewhere. Every aspect of man’s life is about pleasing the One who created him with and for a specific purpose (Revelation 4:11).
The Lord detests murmuring. He hates it so much that He sent fire among the Israelites because of their murmurings (Numbers 11:1). In the New Testament, He warned believers to avoid falling prey to the same sin as the Israelites (1 Corinthians 10:1-14). Additionally, New Testament believers are admonished to do all things without murmurings (Philippians 2:14-16). People murmur as they focus on events within their lives rather than upon the Lord and His word. Yet, the Christian’s life events are ultimately brought to pass, either directly or indirectly, by a loving and caring God. The Lord abhors murmuring because it directly insults His working and provision in our lives.
