If the holy law of God (the ten commandments) reveals that lofty and true standard of living which is required to please the Lord, then the Beatitudes display the attributes of a Christian, broken by the Law and seeking to honour the Christ by faith, keeping His commandments through Him.
The Christian will, in different degrees and at different times have all the elements of being spiritually poor, mourning, meek, hungry, merciful, pure, peacemaking, persecuted and slandered. Of course, these attributes were perfectly lived out by the Incarnate Word, Jesus Christ, but Christians will have these attributes reflected in their souls as they look to Him.
And yet, there is that abiding fear that not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven (Mt 7:21). The more one progresses along the narrow way (v.14), the more one needs to lose self in Christ, and throw out all that may be weighing one down and impeding pilgrim’s progress.
Due to our old nature, our indwelling sin, we need His providential overruling and guiding hand to help our new natures along; thus, in times of sickness we feel closer to Him, in times of loss we cling more sincerely to Him, and in times of disappointment and despair we remember to fear not, thou worm Jacob, and ye men of Israel; I will help thee, saith the LORD, and thy redeemer, the Holy One of Israel (Is 41:14).
