God speaks to you when you quit speaking ill of yourself and begin to believe God in all He says about you. He speaks for you when you don't speak for yourself but believe in His ability to defend your cause. He speaks through you when you empty yourself of all other nefarious foreign voices clamoring to use your vocal cords to advertise their frowsty activities cum businesses. He speaks with you when you speak as He speaks, in line with His words. So, speak with God, for God and by God's name and watch every spoken word of yours come alive!
....Rev. Br. Kenneth Chigozie Alamezie, BSS

God communicates by remaining invincible

It doesn't have enough manners to say "you are welcome" when you thank it for something you think it did.

It communicates through pastorpreneurs and imams who charge 10% it's gullible followers' salaries for it's service.

It communicates by NOT existing

sorry dear, but the mere fact that you live in a world that you know nothing of its formation, that you were once but a tiny fetus which has grown into a full fledged man, perhaps the reason you find it easy to insult your maker, that you will die someday unknown to you, that you don't understand anything about how the world really came to be and runs its course, that you are alive even when you haven't any meaningful contribution to it, that you don't see the Supreme Being, God, whom you ignorantly deny His existence, that you accept the existence of infernal spirits, that you feed on what you never brought to being, that you never had to choose your parents or place of birth, that you must breathe in air and let out same to live, that you are ignorant now yet may get wiser sooner, that the Sun, Moon, and Stars have not ceased in carrying out their duty from day one, that....I could go on and on...unquestionably shows the existence of a GOD who loves you more than you even love yourself.
