“We do not dare to classify or compare ourselves with some of those who commend themselves. But when they measure themselves with one another, they do not show good sense” 2 Corinthians 10:12 (NRSV)
Everyone has some elements of pride within, and these show up often in many cases, such as when we achieved something remarkable, and we feel the need to show off, so that those around us can see us.
This is good to some limit, I mean to some point, because when a show off becomes too much, it leads to sin and of course many nasty reactions.
To be happy about something is great BUT to take pride in showing off is very bad. You are a Christian, and for this, your joy must be centred in the Lord, and whatever achievement you have in life, you must boast in the Lord about this.
When you get to the point that you begin to commend yourself, saying that you do all and achieve all by your own power, then indeed, and just like the last words of the verse states, YOU HAVE NO GOOD SENSE.
Learn to boast in the Lord; do not commend yourself to an extreme. Show to God that to Him be all the adoration and honour. He is the one who raises you. It is not by your power or self that you achieved your goal or whatever.
Without God by your side, I bet you wouldn’t have make it this far, so do not be so ungrateful but comment God and avoid boasting. It is not for the child of God.
