One of the benefits of inclusion in the kingdom of God is knowledge of its secrets. Although the kingdom of heaven was only as yet near, Jesus gave special knowledge of it to his disciples. When asked why he spoke in parables, “He replied, ‘Because the knowledge of the secrets of the kingdom of heaven has been given to you, but not to them’” (Matthew 13:11, NIV). Jesus made it clear, as recorded in Mark 4:11-12 (NIV), that it was his intention that those who were not his disciples would not be able to understand his teaching about the kingdom of heaven. “He told them, ‘The secret of the kingdom of God has been given to you. But to those on the outside everything is said in parables so that they may be ever seeing but never perceiving, and ever hearing but never understanding; otherwise they might turn and be forgiven!’” There are similar words in Luke 8:10.
There are other benefits of the kingdom. Paul told the Thessalonians, “You are witnesses, and so is God, of how holy, righteous and blameless we were among you who believed. For you know that we dealt with each of you as a father deals with his own children, encouraging, comforting and urging you to live lives worthy of God, who calls you into his kingdom and glory” (1 Thessalonians 2:10-12, NIV). Being in the kingdom of God means that we have help in becoming holy, righteous and blameless not just from reading the words of Paul but by the call of God to enter his kingdom and partake of his glory.
Another feature of the kingdom of heaven is that it is unshakeable. We are told this in Hebrews 12:28 (NIV). “Therefore, since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe.”
