“Your kingdom come, your will be done, on earth as it is in heaven.” Matthew 6:10
You are powerful. So much more powerful than you could ever imagine, God has placed us here to usher in His Kingdom, He has trusted us as his ambassadors here on earth, kingdom representatives (2 Corinthians 5:20). God has not asked us to bring his kingdom purely by preaching, teaching and speaking but by signs, wonders and miracles even more amazing than Jesus did himself (John 14:12)! You may not feel like it, but you are a kingdom ambassador, empowered and enabled to bring Jesus into any situation you face and see it changed in his presence.
It is in understanding that it is not you, but Christ in you that makes this possible. He is the power; we are the conduits to see the world blessed! Take the pressure off, realise the presence of Jesus everywhere, and see His love for everyone, you will soon enough see His Kingdom Come! Simple!
