Healing can sometimes be instant and sometimes progressive. Though, I believe God wants to get much of the unbelief out of the church, so we see many instant ones.
Healing can be progressive because we are in a spiritual battle. The enemy doesn’t want us free from sickness, able to do God’s will. The thief wants people bound with sickness to be kept from doing His will. And of course it is His will for ALL His children to be able to do His will, and He made provision for ALL His children to do so – “By His stripes, we WERE healed,” (1 Peter 2:24).
We can apply God’s Word to our bodies like medicine, like salve as it is life and health to our bodies and see healing take place according to our faith, taking Him for His Word and not what is seen.
It’s what God’s Word says, not what man thinks or deduces based on experience. Time for healing to manifest doesn’t negate that His Word is fact and trumps the natural realm. Many that God called righteous because of faith waited for the things they were promised to come to pass. We must be like Abraham who considered not the deadness of his elderly body nor Sarah’s womb and BELIEVED God when He said He’d make him a father of many nations.
My son, give attention to my words;
Incline your ear to my sayings.
Do not let them depart from your eyes;
Keep them in the midst of your heart;
For they are life to those who find them,
And health to all their flesh.
