We tend to project our own feelings onto God, don't you think? I guess it's part of our upside-down training to see Source as anthropomorphic, and hence it's tempting to put conditions and limitations on forgiveness and gratitude. Seeing myself as a reflection of God is a great first step in developing spiritual sense, but it's easy to think that God is a reflection of me! I may feel that I can never forgive certain things because they're just too bad. But God "is of purer eyes" than to see these things, so there is nothing to forgive when I'm living in Oneness. My beliefs may tell me I'm grateful that things aren't as bad as they could be, but God's creation is only good. And so anything unlike God, good, is unreal. Mortal mind, or ego, would tell me many other stories, but I choose to listen to Truth. My gratitude, your gratitude, God's gratitude -- it's all One and the same, as is the Love which conveys it!
“This is what is meant by seeking Truth, Christ, not ‘for the loaves and fishes,’ nor, like the Pharisee, with the arrogance of rank and display of scholarship, but like Mary Magdalene, from the summit of devout consecration, with the oil of gladness and the perfume of gratitude, with tears of repentance and with those hairs all numbered by the Father.”
Mary Baker Eddy - Science & Health Page 367:10-16
“You are being blessed by every beneficent thought of any of your brothers anywhere. You should want to bless them in return, out of gratitude. You need not know them individually, or they you. The light is so strong that it radiates throughout the Sonship and returns thanks to the Father for radiating His joy upon it. Only God’s holy children are worthy channels of His beautiful joy, because only they are beautiful enough to hold it by sharing it. It is impossible for a child of God to love his neighbor except as himself. That is why the healer’s prayer is: Let me know this brother as I know myself.”
