Elisha's miracles show he carries the same power as Elijah before him (1Ki.2:9): Elisha's multiplication (2Ki.4:1-7, 42-44) and purification (2Ki.4:38-41) of food are reminiscent of Elijah's provision for the widow of Zarephath (1Ki.17:7-16); Elisha raising a child from death (2Ki.4:8-37) is similar to Elijah raising the widow's son (1Ki.17:19-23).
Their miracles demonstrate that each is an anointed prophet, a man of God (2Ki.4:7, 9, 16, 1Ki.17:24 etc.)
And they point towards the miracles of Jesus, the ultimate anointed prophet, the man who is God - food multiplication (Jn.6:1-14), raising a child (Mk.5:35-42) and so on.
Miracles restore nature; they don't change it altogether. God is the Creator and all that He created is good (Gen.1:31): He made a world with plenty of food; He gave life to man; He made breath, sight, strength (see 2Ki.4:34).
Miracles restore creation's goodness. This is why the miracles of Elijah, Elisha - and Jesus - have common themes: provision, healing, commanding nature, reversing death.
Yet - and this is fascinating in itself - the man of God has imaginative freedom to perform miracles differently... Borrow some jars? Send a staff with your servant? Lie on a corpse? Throw flour in the pot? Use a boy's lunch? Smear mud on blind eyes? God works with and through His man to right wrongs and restore creation.
It made me ask what 'imaginative methods' for miracles I have experienced, why such inspired originality might be important, and how we can grow our faith.
