Proverbs 10:9 People with integrity walk safely, but those who follow crooked paths will slip and fall.
Integrity is defined as "The quality of being honest and having strong moral principles; moral uprightness." God protects us when we walk with integrity.
We have all had those times in our lives when people that were doing so much wrong seemed to be the ones flourishing. The key is not to let their wrong doing effect the way we live our lives. No to get that "it doesn't matter anyway" attitude. It does matter, it matters to God, it matters to our well being. In the end God will protect us if we live our lives with integrity. It is not always easy, but it is always, always worth it!
Remember the blessings that God sends down from heaven are far greater than anything we can imagine, anything we can accomplish on our own.
