The real righteousness that the Kingdom will give us is a righteousness by faith in Jesus Christ, a righteousness based solely on what he's done. The righteous acts we'll do, the righteous living we seek to have, will come about because God enables it, because his Spirit empowers us in our daily living. Blessed are the merciful, for they will receive mercy. The first four blessings have spoken of God's mercy for the helpless, but now the shoe's on the other foot, or to fit in better with this time of year the ball is in our court. There are 2 ways that you could respond.
Some people respond by a rigid demand for righteousness.
They say, look at how Jesus told you to live. You'd better keep up to that standard or you're in big trouble. On the other hand, the word of the gospel is a word of mercy. Blessed are the pure in heart, for they will see God. We know, don't we that it's only the pure in heart who can come into God's presence and live.
