Shouldn't we be seeing the Kingdom of God advance?

In the Lord’s Prayer we have the phrase “Thy Kingdom come. Thy will be done in earth, as it is in heaven.” Now just before giving us this model prayer Jesus instructed His followers not to use vain repetitions. Considering that this prayer has been prayed for over 2000 years, and given the warning not to use vain repetitions, we can conclude that the Kingdom is here among us today, and that it is not limited to an event off into the distant future. However, if this is so, if the Kingdom is amongst us today, if it is breaking out, some may ask the question “shouldn’t we be seeing signs of its progress? Shouldn’t we be seeing the Kingdom of God advance rather than the power of evil?”
