We do not know for sure why someone would sneeze 7 times because we only sneeze while raging with a flu. But ever heard of the Sneeze of life? You've probably never heard of a dead person being brought back to life with sneezing.
Well, 2 Kings 4:18-37 gives us an incredible scenario of faith and life. How strong is your faith?
So was the faith of [the Shunammite] rewarded. Christ, the great Life-giver, restored her son to her. In like manner will His faithful ones be rewarded, when, at His coming, death loses its sting and the grave is robbed of the victory it has claimed. Then will He restore to His servants the children that have been taken from them by death. {PK 239}
Sabbath blessings.
