How do a deaf person accept christ?

People with disabilities are still capable of hearing or reading the gospel of their salvation (1Cor 15:1-4, Eph 1:13, & 2:8-9) with the help of other believers.

It is so important to emphasis to a person seeking salvation in Christ that it is free gift from God to us believed by faith only (Rom 6:23 & Eph 2:8-9)

If we add others things to salvation like water baptisms or seeking signs like speaking in tongues then how could a person with physical disabilities ever be able to perform these things --- it would put them off ever getting saved.

By being delusional and believing in fairy tales.

No one has to be informed that gravity is real, but if you were never indoctrinated you would never conclude from your own observations or experiences that this Jesus character was real..which proves that it's a load of BS

By believing in the Lord Jesus Christ.  They read John 3:16 and 1 Corinthians 15:3-4, and they believe it.  The Lord Jesus Christ is God, and He loves you.  Believing in the Lord Jesus Christ means being forgiven all sins past and future, and means going to heaven and not hell.  Death leads to immediate heaven or hell, and it is too late to be saved, after death.  All believers still sin.  See 1 John 1:8.  To be in heaven and not hell, believe in the Lord Jesus Christ, who is God and who died on the cross and shed His blood to pay for all of our sins in full, and who was buried, and who resurrected from the dead.  The only way to avoid hell is by believing in the Lord Jesus Christ, without adding any of your own works.  See Romans 4:5, 1 Corinthians 15:3-4, and John 3:16.
