Mixture of scholarly notes blended with some knowledge/insight that you can gather in your walk as a Christian. The highlighted passages that rang in my soul and wowed me:

"Real forgiveness means looking steadily at the sin, the sin that is left over without any excuse, after all allowances have been made, and seeing it in all its horror, dirt, meanness and malice, and nevertheless being wholly reconciled to the man who has done it." (C.S. Lewis, The Weight of Glory from Words to Live By p. 123).

He speaks on difference between excuses vs. forgiveness. (It spoke to me and hope it does for you too). Forgiveness says, "Yes you have done this thing, but I accept your apology, I will never hold it against you and everything between us two will be exactly as it was before." But excusing says, "I see that you couldn't help it or didn't mean it, you weren't really to blame."

"Christians say the Christ-life is in them, they don't mean simply something mental or moral. When they speak of being "in Christ" or of Christ being "in them," this is not simply a way of saying that they are thinking about Christ or copying Him. They mean that Christ is actually operating through them; that the whole mass of Christians are the physical organism through which Christ acts--that we are His fingers and muscles, the cells of His body." (C.S. Lewis, Words to Live By p. 30).

"The three things that spread the Christ life to us: baptism, belief, and mysterious action which different Christians call by different names--Holy Communion, the Mass, and the Lord's Supper." (C.S. Lewis, Words to Live By, p. 32).

"God whispers to us in our pleasures, speaks in our conscience, but shouts in our pains: it is His megaphone to rouse a deaf world. The voice of God indeed daily calls to us; calls to the world to abandon sins and seek the Kingdom of God wholeheartedly." (p. 139)
