Read: 1 Corinthians 1:31
Boasting is a common trait found in worldly people. People boast about their achievements, skill, power, wealth, physical appearances, family heritage, etc. All these are worldly boasting. God has spoken through prophet Jeremiah, “Let not the wise man glory in his wisdom, let not the mighty man glory in his might, nor let the rich man glory in his riches; but let him who glories glory in this, that he understands and knows Me, that I am the Lord, exercising loving kindness, judgment, and righteousness in the earth. For in these I delight, says the Lord” (Jer. 9:23-24).
Earlier the whole world had one language and common speech. The people became boastful and proud saying, “Come, let us build ourselves a city, and a tower whose top is in the heavens; let us make a name for ourselves” (Gen. 11:4). God confused their language and scattered them, that they could not finish building the tower reaching the heavens. Goliath boasted of his strength as he approached David, “Am I a dog that you come at me with sticks? Come here, I will give your flesh to the birds and wild animals.” But David boasted in the Lord saying, “You come to me with a sword, with a spear, and with a javelin. But I come to you in the name of the Lord of hosts, the God of the armies of Israel, whom you have defied. This day the Lord will deliver you into my hand, and I will strike you and take your head from you. And this day I will give the carcasses of the camp of the Philistines to the birds of the air and the wild beasts of the earth, that all the earth may know that there is a God in Israel. Then all this assembly shall know that the Lord does not save with sword and spear; for the battle is the Lord’s, and He will give you into our hands” (1 Sam. 17:45-47). God gave David victory over the Philistine Goliath.
Paul the apostle wrote to the Corinthian believers, “God has chosen the foolish things of the world to put to shame the wise, and God has chosen the weak things of the world to put to shame the things which are mighty” (1 Cor. 1:27). We have nothing to boast about except in the Lord as “I can do all things through Christ who strengthens me” (Phil. 4:13). Through His strength, you will be able to do the most impossible things for His glory.
