Of course, God encourages man to think. This may come as a shocker to many but the Lord does not want man to blindly accept information without first giving it thought. During the Lord’s earthly ministry, He often asked men what they thought (Matthew 17:25; Matthew 18:12; Matthew 21:28). His purpose was not because He valued men’s opinions; but, rather, to cause men to think. The problem for the Lord is not that man thinks, but that man thinks and focuses upon the wrong things. God has specific things upon which He wants man to ponder. These involve things that are true, honest, just, pure, lovely, of good report, virtue, and praise (Philippians 4:8). As such, believers should focus their attention upon these righteous thoughts rather than those thoughts espoused by the world, the flesh, and the devil.
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.
