Ephesians6:10-20 talks about how we need to put on the whole armor of God... that we go up against principalities and powers....

When I first was dx's with a disabling illness, I sunk myself in the book of Job ( who became my hero).... God is not the one who tests us and puts things upon us.. it is satan.... as a test of our faith in God....

I can't understand everything either but I do know in my heart that God is a loving God and He wants us to be healthy and happy and sometimes that just isn't possible...for whatever reason He allows things to happen and we must remain faithful....

Psalm138:7.... "Though I walk in the midst of trouble, You will revive me You will stretch out Your hand against the wrath of my enemies.. and Your right hand will save me"

David the Psalmist had faith even in the midst of hiding from his enemies.. those who sought to kill him... read in Psalms about his faith. it is inspirational.

Stay strong hun... God will deliver you in His time... I will be praying for you...Faith
