God already showed us in scriptures what it means for us to be His children, and what it costs us to follow Him. In many ways, the Cross of Jesus Christ is the way of Christian Life. He humbled Himself to the cross and sacrificed His own life for us, He suffered for our sake, He endured all kinds of rejection from His own people. In this passage, we see how the Cross becomes the model for christian life.
Christianity doesn’t demand us to perform many rituals and sacrifice to Idols or become a monk, but it demands us to forsake our selfishness and pride; only then are we able to believe that Christ is the only Savior of our lives because we couldn’t save ourselves from God’s righteous judgment. In this passage we learn how God chooses unintelligent people, people with low social status, people who are not very influential, demonstrating His grace to those who are helpless and crushing the pride of those who believe they are self-sufficient, wise and powerful enough.
