Believers should thank God for the precious gift of unity, which is a result of the specific prayer Christ prayed in John 17. We are to be of one mind, without haughtiness, as stewards of the manifold grace of God. God forgives us as we forgive others, and gives us His grace: therefore, we can afford to give it to others. We respond to divine grace, without works.
When the disciples were all in one place, power came upon them by the Holy Spirit (2); (3), and this power sent the Church into Jerusalem and Judea as well as to the uttermost parts of the world. The early church was at rest; they edified one another, and walked in the fear of the Lord. They went forth praising God, while dwelling in peace. As they rested in the finished work, the Word of God was multiplied.
Unity will not be established unless individual members of the Body of Christ are filled with the Holy Spirit (4). When a believer is filled with the Spirit, he will not be easily wounded. “Great peace have they that love thy law: and nothing shall offend them” (Psalm 119:165).
When the Body of Christ experiences this, nothing can stop the cause of the Gospel! Whenever division is destroyed and unity is established for the sake of Christ, believers can proceed unhindered in progress to fulfill the Great Commission.
