With the same knife if a robber has it in his hand, it is considered as a weapon, while if a mother draws it, it is a useful tool for her beloved husband and children. In the same manner, there is a great difference between the insight of a wicked man and that of a good man. For example, with a beautiful jewel a wicked man covets to steal it but a good man is reminded of the kingdom of heaven as beautiful as crystal. If you look at and think everything with goodness, life itself is the kingdom of heaven to you.
