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.
The Bible does not command Christians to sacrifice truth and pursue unity among people in the church, and neither does it command us to pursue only truth and not unity. Fundamental truths of the Bible and unity are different sides of the same coin. It is ultimately the gospel which unites us to Christ and His church. In this sermon, we learn about the nature and the need for Christian unity.
