Pastor , How about those was born mute and deaf, how are they going to speak it? And those who was born with verbal disability like autisme and down syndrome? How these ppl are going to say it, speak it? These people couldn't communicate with sign language.
you may watch again, Pastor has mentioned: when you KNOW HIM by reading His word for what HE HAS DONE (via Bible), resulting in having FAITH in HIM, and SPEAK/DECLARE in faith to RECEIVE HIS GRACE. i.e., KWON HIM--> HAVE FAITH IN HIM--> DECLARE/SPEAK IN FAITH--> RECEIVE. May God grant you wisdom and grace to know HIM. God bless you :)
