WHY IS IT IMPORTANT for us to know that there is "no wickedness"--no unrighteousness--in the Lord?

Knowing that God is not wicked is important not only in our own lives but also when we have opportunity to share our faith. The Lord alone is good, and there is no wickedness in him. People are often resistant to Jesus because there is still wickedness in the world. If we are secure in the goodness of God, it will strengthen our faith and our ability to share it.
