Agape is the love of God operating in the human heart. When we rise to love on the Agape level, we rise to the position of loving the person who does the evil deed, while hating the deed the person does.
There is no effort that we can make to still ourselves. True stillness comes naturally from moments of solitude where we allow our minds to settle. Just as water seeks its own level, the mind will gravitate toward the holy. Muddy water will become clear if allowed to stand undisturbed, and so too will the mind become clear if it is allowed to be still.
