My heart

Thy word is a lamp unto my feet, and a light unto my path. I have sworn, and I will perform it, that I will keep thy righteous judgments. I am afflicted very much: quicken me, O Lord , according unto thy word. Accept, I beseech thee, the freewill offerings of my mouth, O Lord , and teach me thy judgments. My soul is continually in my hand: yet do I not forget thy law. The wicked have laid a snare for me: yet I erred not from thy precepts. Thy testimonies have I taken as an heritage for ever: for they are the rejoicing of my heart.

The heart of man…

Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren. But whoso hath this world’s good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him? My little children, let us not love in word, neither in tongue; but in deed and in truth. And hereby we know that we are of the truth, and shall assure our hearts before him. For if our heart condemn us, God is greater than our heart, and knoweth all things.
