Years ago I developed a health issue that set me back very farther than I should have been in life but I worked extremely hard to improve my health and in 2015, God began to heal me, but it’s not all bliss. I ended up parading my good fortune as if I had earned it and not understanding others who were never healed and sometimes I blamed extremely bad people with health struggles for their issues saying the deserved to be sick. While it might be true they deserved to be sick, I was an imperfect person who also deserved to be sick. I ended up with other issues that were similar to the ones I recovered from, very mild and insignificant, but potentially insidious if not limited or dealt with or healed and the bible says if you continue to sin once atonement has been made, you lose all the benefits of the atonement God has given you and might be even worse off than what you were before.
My friend from school knew a guy with a very severe illness and one day he converted to Christianity and his health issues disappeared. But then, he went back to his old sins and turned his back on God and his health problems came back. The same thing happened to other converts I knew: They converted when God healed their sick family members but when they went back to their old sins, their family members became sick again.
If you want God’s blessing to be real, your remorse and repentance and devotion and loyalty has to be real. Then and only then, can you trust in God‘s miracles.
