„Try to spend at least one day keeping the commandments of God and you will realise yourself. Your heart will tell you how good it is to do God’s will (and for us to do God’s will means life, means eternal bliss). Love God with all your heart; at least as you love your relatives and your well-doers: value as much as possible love and kindness that He shows you, His great and countless blessings.
Try to grasp these with the heart: how He woke you to life, sharing all His good things, how He endures your sins endlessly, how He forgive them endlessly, waiting for your wholehearted repentance, in the power of His sufferings on the Cross and of His death, the Son of God, the One Borned; remember the eternal happiness promised you if you remain faithful.
Love everyone as you love yourself, namely do not deny anything that you do for yourself, banish from the heart all remembrance of the evil that the others have done to you, just as you would want others to forget the evil you have done them.“
(St. John of Krondstadt – My life in Christ)
