Giving our very best for the God's glory and for His kingdom is commendable. Godly ambition of this nature is praise worthy; but worldly competition is based on a false sense of values. Self-exaltation birthed in pride neither honors God nor His kingdom.

Matthew 5:16 KJV

Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.

1 Corinthians 3:3 King James Version (KJV)

3 For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?
