Proverbs 10:3 The LORD will not suffer the soul of the righteous to famish: but he casteth away the substance of the wicked.
We know that God takes care of his people and we will never have to worry about the problems we have because they are there to strengthen us. Also we are promised an eternal home with Him in heaven. The wicked so many times seem like they get away with everything but in time God will also deal with them.
Psalm 37: 22 For such as be blessed of him shall inherit the earth; and they that be cursed of him shall be cut off.
23 The steps of a good man are ordered by the LORD: and he delighteth in his way.
24 Though he fall, he shall not be utterly cast down: for the LORD upholdeth him with his hand.
25 I have been young, and now am old; yet have I not seen the righteous forsaken, nor his seed begging bread.
26 He is ever merciful, and lendeth; and his seed is blessed.
27 Depart from evil, and do good; and dwell for evermore.
28 For the LORD loveth judgment, and forsaketh not his saints; they are preserved for ever: but the seed of the wicked shall be cut off.
