Don't get me wrong on this.. I'm not at all telling you to serve when you are sick. Don't want to play Lord. I'd like to see you obey God first, and to be honest..also get to a pastor and a doctor that He leads you to. Not sure how it will go with you, how could I, but you can always trust the Lord. I'd say ask Him for wisdom and choose to apply.. to act wisely in obeying the Lord. Sure, daily obey Him more than you would any other human.
I've seen and met my own fleshly nature before. Not handsome. I've seen my selfish ways before, and how much I lack spiritually, but I've also come to understand that God gives. He is the Giver of all givers. I wasn't born that way, but now want Him to give through me. And I cannot out-give him. Jesus gives and gives and gives some more. He will give me what I need when I need it. Even promised to do that for us and by faith we can claim that promise!
But God by His Spirit can also speak to our hearts if we let Him and He can give us wisdom for all kinds of different giving. He can show us step by step how to pull off what seems very impossible ..and He can give grace on a moment by moment regular basis. I'm an ordinary dude, but He's spoken to my heart before.. to give all of me to Him.. to give when it costs a lot and when it's not even convenient. But it's instead a big sacrifice for me. But listen.. you know that Jesus has of course sacrificed far more than me or you. I admit I haven't always obeyed Him, but I sure want to now. I believe that we are living in the last days when it's so crucial to obey God's Word.
Don't even let the weird scam-tactics or pressure from money-grubbing televangelists (I mean the false teachers) presumptuously lead you to give with your credit card etc. That also would be sin. Jesus is your Lord who cares about you, not them.
Study and remember how God used Corrie Ten Boom. She kept ministering and serving the Lord with joy inside that lice-ridden Ravensbrück Nazi concentration camp. Listen, these ideas and gentle warnings didn't originate with me, no no, but you and I can still be involved in sharing as Corrie did.. yes, in this kinda Spirit-led giving or wise non-giving even while we're perhaps still feeling pretty needy. And I pray that God will indeed bless and specifically meet your needs real soon, so you too can continue on with JOY! The Bible says...
