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).
We could continue to try to extrapolate conclusions for our own lives based on the events which surrounded Christ's birth. But there's going to be quite a bit of subjective guesswork involved. Or, we could just look at passages that actually speak to us directly concerning these matters.
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).
