Although Sophie Amalie died 30 November 1695 without having borne him a male heir, John Charles wrote Christian on 25 July 1696 declaring that if, feeling unable to continue living alone and heeding his heart's desire, he were to remarry it would only be a marriage of affection, since he was in no position to maintain a lady of rank.
Kuigi Sophie Amalie suri 30. novembril 1695 ilma talle meessoost pärijat ilmale toomata, kirjutas Johann Karl 25. juulil 1696 Christianile, kuulutades, et kui ta, tundes võimetust jätkata üksi elamist ja võttes kuulda oma südame soovi, peaks uuesti abielluma, saab see olla vaid kiindumusabielu, kuna ta ei olnud seisundis hoida seisuslikku naist.
