From Pope Francis’ Little Book of Wisdom
If we——all of us——accept the grace of Jesus Christ, He changes our heart and from sinners makes us saints. To become holy we do not need to turn our eyes away and look somewhere else, or have as it were the face on a holy card! No, no, that is not necessary. To become saints only one thing is necessary: to accept the grace that the Father gives us in Jesus Christ. There, this grace changes our heart. We continue to be sinners for we are weak, but with this grace which makes us feel that the Lord is good, that the Lord is merciful, that the Lord waits for us, that the Lord pardons us—-this immense grace that changes our heart.
