There is no time to hid things within our hearts that have no benefits to us. We have to grow! We want to grow! Our heart have to have blood to flow which keeps us alive. In the spiritual sense what is keeping you alive? How are you growing spiritually? What have you hid in your heart? foolishness? stubbornness? distrust? no patience? If so, these things will not allow you to grow.  Hide in your heart; love, gentleness, patience, happiness, peace... You have to grow!
