All of God’s emotions, including His love in all its aspects, cannot be divorced from God’s knowledge, God’s power, God’s will. If God loves, it is because He chooses to love; if He suffers, it is because He chooses to suffer. God is impassible in the sense that He sustains no “passion,” no emotion, that makes Him vulnerable from the outside, over which He has no control, or which He has not foreseen.
