When it seems like wickedness is prevailing, be encouraged by this:
When the wicked spring as the grass, and when all the workers of iniquity do flourish; it is that they shall be destroyed for ever. Psalm 92:7
The truth will stand for ever. Wickedness is only temporary. Wickedness may seem to be flourishing, but it will be destroyed. Righteousness will prevail. There will be a happy ending in all this, for God is perfectly just and perfectly compassionate. He perfects the combination of mercy and truth.
Truth shall spring out of the earth; and righteousness shall look down from heaven. Yea, the LORD shall give that which is good; and our land shall yield her increase. Righteousness shall go before him; and shall set us in the way of his steps. Psalm 85:11-13
Fret not thyself because of evildoers, neither be thou envious against the workers of iniquity. For they shall soon be cut down like the grass, and wither as the green herb. Trust in the LORD, and do good; so shalt thou dwell in the land, and verily thou shalt be fed. Psalm 37:1-3
Rest in the LORD, and wait patiently for him: fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass. Cease from anger, and forsake wrath: fret not thyself in any wise to do evil. For evildoers shall be cut off: but those that wait upon the LORD, they shall inherit the earth. For yet a little while, and the wicked shall not be: yea, thou shalt diligently consider his place, and it shall not be. But the meek shall inherit the earth; and shall delight themselves in the abundance of peace. Psalm 37:7-11
I have seen the wicked in great power, and spreading himself like a green bay tree. Yet he passed away, and, lo, he was not: yea, I sought him, but he could not be found. Psalm 37:35-36
Remember what Jesus said:
Blessed are the poor in spirit: for theirs is the kingdom of heaven.
Blessed are they that mourn: for they shall be comforted.
Blessed are the meek: for they shall inherit the earth.
Blessed are they which do hunger and thirst after righteousness: for they shall be filled.
Blessed are the merciful: for they shall obtain mercy.
Blessed are the pure in heart: for they shall see God.
Blessed are the peacemakers: for they shall be called the children of God.
Blessed are they which are persecuted for righteousness’ sake: for theirs is the kingdom of heaven.
Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.
Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.
Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.
Ye are the light of the world. A city that is set on an hill cannot be hid.
Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.
Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
