Or in NIV
"I've had it with you! You're hopeless, you religion scholars, you Pharisees! Frauds! Your lives are roadblocks to God's kingdom. You refuse to enter, and won't let anyone else in either."
"Woe to you, teachers of the law and Pharisees, you hypocrites! You shut the kingdom of heaven in men's faces. You yourselves do not enter, nor will you let those enter who are trying to."Or Young's Literal Translation
"Wo to you, Scribes and Pharisees, hypocrites! because ye shut up the reign of the heavens before men, for ye do not go in, nor those going in do ye suffer to enter. "
I just came across this verse that I had somehow missed before when I was examining verses about the kingdom of heaven, or kingdom of God. This verse confirms the idea that the Kingdom of Heaven is now - starting in the days of Jesus. Everything in the verse seems to be in the present tense.
May we all seek to enter God's kingdom and live under God's reign. And may we not be roadblocks to others.
