In John 17:11, Jesus prays to the Father, saying, "And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are."

This verse is from Jesus' high priestly prayer, which is often referred to as the "real Lord's Prayer." It occurs during the Last Supper, just before Jesus is crucified. In this prayer, Jesus intercedes for his disciples, seeking God’s protection for them as they go out into the world to fulfill the Great Commission. He prays for their unity and for the preservation of their faith in the face of persecution and tribulation.

The context of this verse is crucial to understanding its significance. Jesus is about to leave the world and return to his Father in heaven. He is entrusting his disciples, and by extension all believers, to the care and protection of the Father. The unity Jesus prays for is not just a shallow, superficial unity, but rather a deep, abiding unity that reflects the perfect unity between God the Father and God the Son.

One of the key themes of John 17:11 is the concept of unity among believers. Jesus prays for his followers to be one, just as he and the Father are one. This unity is not just a matter of getting along or having a common purpose; it is a unity of spirit, love, and purpose. It is a reflection of the unity within the Trinity and is intended to be a witness to the world of the power of the gospel to create true community and solidarity among believers.

Another important theme in this verse is the power of God to keep and protect those who belong to him. Jesus asks the Father to keep his disciples through his own name, showing that the Father’s power and authority are at work in the preservation of believers. This prayer reflects the reality of spiritual warfare and the need for divine protection against the forces of darkness and the trials and tribulations of life.

The symbolism in John 17:11 is rich and profound. The image of the disciples being in the world while Jesus is no longer in the world points to the tension between the kingdom of God and the fallen world. The disciples, like all believers, are called to live in the world but not be of the world, to be a light in the darkness without being contaminated by the darkness.

The reference to the Father as "Holy Father" emphasizes the holiness and purity of God. It speaks to the perfect righteousness of the Father, which is to be reflected in the lives of believers as they seek to live in unity and obedience to God’s will.

Finally, the concept of being one, as the Father and the Son are one, is a profound mystery that speaks to the nature of the Godhead and the unity of purpose and will within the Trinity. It also speaks to the potential for unity and community among believers, despite the diversity and differences that may exist among them.

In conclusion, John 17:11 is a powerful and profound prayer of Jesus for the unity and protection of his disciples and all believers. It reminds us of the importance of unity in the body of Christ, the power of God to preserve and protect his people, and the ultimate goal of reflecting the unity and love of the Trinity to a watching world. It is a prayer that continues to resonate and inspire believers to seek and embody the unity for which Jesus prayed.
