Why is humility important for Christians according to the sermon?

The sermon points out that humility is foundational in the life of a Christian. In Matthew 18:4, Jesus states that those who humble themselves as little children are the greatest in the kingdom of heaven. This humility counters the pride and self-righteousness that can arise in our hearts, which are often rooted in ignorance of our need for God. A humble heart acknowledges one's complete dependence on God's grace, acknowledging that all one has is received from Him. By striving to be humble, Christians embody Christ’s character, who exemplified ultimate humility and service, urging believers to become servants to one another.
