No longer do I call you servants, for a servant does not understand what his master is doing. But I have called you friends, because everything I have learned from My Father I have made known to you. — John 15:15
Jesus calls us friends, not servants. A servant doesn't know his master's business, but Christ has revealed everything to us. The Lord shared His plans with Abraham, gave the disciples the secrets of the kingdom, and the Spirit searches the deep things of God and reveals them to us. We who were once far off have been brought near and admitted into the friendship of God. True friends of Christ are those who do what He commands — not earning friendship, but displaying it.
