We want our kids to believe in themselves. We tell them "You can do anything". It is good parenting to encourage our kids. Unfortunately, we fail to see the difference between encouragement and truth sometimes. The truth is that our kids can't do everything. They can surely increase the probability of success by working harder but working hard won't guarantee success. Also, working hard will not save us from our sins.
Lord, thank you for grace and help me to realize that grace alone will save me as long as I am truly repentant.
