Did God really create someone in particular we must marry?
Since God knew us while we were yet in the womb, He also knows who our life-partners are but until we commit all to Him, we're bound to make mistakes most times. You can meet a lady and desire to marry her but you must present it to God and wait for Him to confirm it before proceeding.
In another way, His unseen hands also guides us and when we remain and bear fruits in Him, even without hearing from Him, our minds are so aligned to His that we still make choices but in truth, He's the one actually making the right choices in us and at the end, all was done according to His will.
But when we walk by sight and are captivated by beauty, fame, status, wealth etc., then it becomes hard to listen to God because those things have become an idol in our hearts. So, Yes, our Father in Heaven has a special person to us to marry because He alone sees the future and when we walk with and obey Him, everlasting joy becomes our portion..
