Why is the concept of Christ being rejected important for Christians?

The rejection of Christ serves as a reminder of the pervasive wickedness of humanity that seeks to overthrow God's authority, as articulated in Matthew 21:37-39. This reality reflects our own sinful nature and the necessity for divine grace in our lives. Jesus' rejection by His own people emphasizes the cost of discipleship and the stark reality that true faith may lead to persecution. For Christians, understanding this rejection fosters humility and cultivates a deeper appreciation for grace as the source of our salvation, recognizing that it's through God's providence that we are called to repentance and belief.
