Firstly, there is no record that Jesus was born sick, diseased, or disabled. So I’m not sure how the comment about God wanting us to be healthy relates. Insofar as wealth, Mr. Benge left out the fact that Christ was visited by wise men who brought Him expensive gifts—-including gold (Mt 2:11).
The issue with attempting to extrapolate doctrinal meaning from events in the Bible is it’s going to largely be open to interpretation with no verifiable way to tell whose is correct. This is the same problem we run into with Paul’s thorn in the flesh, Timothy’s frequent illnesses, and a whole host of other recorded instances in Scripture: All we can say for sure is these things happened. Beyond that, it’s essentially a fill-in-the-blank free-for-all.
There is, however, an easier path we could take when it comes to figuring out what God thinks about these issues. And that is to look at what He actually said about them.
James 5 promises the prayer of faith will heal the sick. Doesn’t say maybe. Doesn’t say sometimes. It says the prayer of faith shall heal the sick (vs 15, DBY).
1 Peter 2:24 says we were healed by His stripes.
Mark 16:17-19 says believers will lay hands on the sick and they will recover.
Romans 8:32 asks the question that if God didn’t spare Jesus, how will He not also give us all things along with Him?
1 Corinthians 3:21-22 then confirms that He did indeed give us all things—-not just in the future, but in the PRESENT as well.
2 Corinthians 8:9 says He was made poor so that through His poverty we could be abundantly supplied (AMP).
