Our Proverbs today tells us that strength is found in The Lord.  

Pro 24:16  for the righteous falls seven times and rises again, but the wicked stumble in times of calamity.

Someone who is in the Lord may get knocked down, knocked down more than once…7 times is what the verse says, but God endows His children with the strength so that they rise again.  

On the other had when the wicked person is confronted with bad times, they fall on their face, they don’t have the strength to face adversity.  

When we hear that Word “God is my rock” a rock is unshakeable, rocks withstand bad weather, earth quakes and tsunamis, in other words, a rock is strong.  God gives rock-like strength to those who trust in Him, hence the verse telling us that righteous are strong when tough times strike, but the wicked fold like a cheap suit.
