That God will use Christian people with disabilities. Body of Christ has one Spirit, and different gifts and abilities, Ephesians. Salvation is open to those who have free will. Its personal decision, if new convert will carry there cross daily and follow Jesus. There will be some persecution and hardship at times. Getting deeper here. Galatians chapter 5, be led by the Spirit. Flesh is in conflict with the Spirit. The flesh can't please God,nor know will of God.
Walk in the Spirit. Different functions of body of Christ. One might be good at making money and donates to the poor. Another might be teacher. Another might volunteer at soup kitchen.
2 Corinthians chapter 4
But I have renounced the hidden things of dishonesty, not walking in craftiness, nor handling word of God deceitfully, but by manifestation of the truth commending our selfs to every man's conscience in the sight of God.
Jesus always told the truth. Shepherds are follow Jesus example. Nourish the flock, and teach sound doctrine. Never water down God's word.
1 Corinthians chapter 12
Now there are diversity of gifts, but the same Spirit.
12:8
For one is given by the Spirit the word of wisdom, to another the word of knowledge by the same Spirit. Whether regular Christian or Christian with disabilities. Jesus uses body of Christ to carry out there diverse functions. The eye can't say, I don't need the foot. The weaker member is just as important as the eye of head.
Handicapped Christian people are not indespensanble.
12:15
If the foot shall say, Because I am not the hand, I am not of the body, is it therefore not of the body?
12:21
And the eye can't say to the unto the hand, I have no need of thee, nor again the head to the feet, I have no need of you.
Body of Christ is to edify, and glorify Jesus. Each member has unique gifts.
12:22
And those members of the body, which we Think to be less honorable, upon these we bestow more aboudant honour, and our uncomely parts have more aboudant comeliness.
Yes, the testimony of Christian people with disabilities carrys more weight than normal Christian. Gods wonderful works are displayed through handicapped Christian people.
12:25
There should be no schism in the body but, that the members should have same care for one another.
We are to edify body of Christ. Not tear people down. Flip side of the coin. We must expose fruits of darkness, false brethren. They infiltrate Body of Christ to cause division and damage.
Jesus healed blind, lepers, paralyzed people. I failed trade school back in 1992. My dad thought I might have gift to succeed. He was thinking in the flesh, not led by the Spirit. Again, carnal minded people can't understand spiritual things or discern them. Holy Spirit is absolutely essential. My gift is spiritual. Jesus granted me knowledge and wisdom of God's word. I was in special education through school system, and have autism. Wonder ful works of God. Jesus called me out of the world, to serve him. Those who walk in the flesh can't understand will of God,or spiritual things.
2 Corinthians chapter 5
Therefore if anyone is in Christ, he is new creation, the old has passd away.
Romans chapter 8
You, however are not in the flesh but in the Spirit, if in fact the Spirit of God dwells in you. Anyone who does not have the Spirit of Christ does not belong to him.
The weaker members of body of Christ are not indespensanble. And some people have Spirit of slumber and can't understand deep truth of Gods word. You need holy Spirit. I hope this helps. Peace.
