Hold fast to the confession of your faith. That does not mean stop your dialysis! The word says many things about health and healing.
The first thing is to know what God has already said about His provisions for your health and healing. It is important that you hold fast to these confessions... even when there is no evidence of physical improvement.
Remember in the epistle to the Hebrews.
It is impossible to please God without faith, for those who come to God must believe that He is AND that He is a rewarder of those that diligently seek Him.
Paul then gives many examples of believers who prayed diligently even until they died and yet never saw the answer to their prayers. They did exactly what they were supposed to do. They believed and confessed the word of God, even to the end.
This is what we have to do. Faith is evidence of things not seen. You may not see what you are praying for. But faith believes it is there. Faith professes the truth. It never contradicts what God said. It never believes or says you do not have what He said you DO have.
Many people will tell you this is not true. Many will put qualifications on your healing and health. Do not listen to them. Stand with God. Stand on His word. They will explain away these scriptures and say they are not for you. They ARE!
This is your life. This is your faith. He is your Lord and God. Stand with Him!

My son, give attention to my words; Incline your ear to my sayings.

James 5:14-15 NKJV
Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord. And the prayer of faith will save the sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven.

The devil will come to you and say "hath god said" and try to talk you out of what God has provided for you. Just hit him with these scriptures and do not back up. What have you got to lose?
