The love of God is eternal.
Just as its origins are to be found in eternity past, so too its end is to be found in eternity future.
In other words, it has no end at all.
Paul writes: “Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? As it is written, ‘For thy sake we are being killed all the day long; we are regarded as sheep to be slaughtered.’ No, in all these things we are more than conquerors through him who loved us. For I am sure that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.” (Romans 8:35‑39).
