The heart is refined, spiritual, and heavenly by nature - guard it; do not overburden it, do not make it earthly, be temperate to the utmost in food and drink, and in general in bodily pleasures. The heart is the temple of God. 'If any man defile the temple of God, him shall God destroy' (I Cor. 3:17).

A Christian must always be kind, gracious, and wise in order to conquer evil by good.

A man who is wrathful with us is a sick man; we must apply a plaster to his heart - love; we must treat him kindly, speak to him gently, lovingly. And if there is not deeply-rooted malice against us within him, but only a temporary fit of anger, you will see how his heart, or his malice, will melt away through your kindness and love - how good will conquer evil. A Christian must always be kind, gracious, and wise in order to conquer evil by good.

Divine service, being the high contemplation of the mind, is at the same time, and pre-eminently, the peace, the sweetness and blessedness of the heart.

Love does not reflect. Love is simple. Love never mistakes. Likewise believe and trust without reflection, for faith and trust are also simple; or better: God, in whom we believe and in whom we trust, is an incomplex Being, as He is also simply love.

When you say a prayer, He (The Holy Spirit) is in every word of it, and like a Holy Fire, penetrates each word.

The longer we remain without confessing, the worse it is for us, the more entangled we become in the bonds of sin, and therefore the more difficult it is to give an account.
