Whether a person believes in God or not, deep in his/her heart, he/she might from time to time reason something releated to God.

No matter you know there is a God or not, but in this world there is indeed a true God and false gods.

Here is an interesting description of a false god:

Psm 115:4-8 “Their idols [are] silver and gold, the work of men's hands. They have mouths, but they speak not: eyes have they, but they see not: They have ears, but they hear not: noses have they, but they smell not: They have hands, but they handle not: feet have they, but they walk not: neither speak they through their throat. They that make them are like unto them; [so is] every one that trusteth in them.”

Then you might ask, how about the true God? How to tell the true God from a false god? Actually it is easy to tell the true God from a false one: the true God only gives and does not ask for return: the true God gives us life, the true God gives us air, the true God gives us sun, the true God gives us water..., He will not ask us to pay for the air we breathe, He will not ask us to pay for the sunshine we enjoy, ...., the true God only gives, because everything is His, if He indeed needs something He does not need to tell us, but there is one thing He would delight to have: that's our thanksgiving:

Psm 50:7-15: Hear, O my people, and I will speak; O Israel, and I will testify against thee: I [am] God, [even] thy God. I will not reprove thee for thy sacrifices or thy burnt offerings, [to have been] continually before me. I will take no bullock out of thy house, [nor] he goats out of thy folds. For every beast of the forest [is] mine, [and] the cattle upon a thousand hills. I know all the fowls of the mountains: and the wild beasts of the field [are] mine. If I were hungry, I would not tell thee: for the world [is] mine, and the fulness thereof. Will I eat the flesh of bulls, or drink the blood of goats? Offer unto God thanksgiving; and pay thy vows unto the most High: And call upon me in the day of trouble: I will deliver thee, and thou shalt glorify me.

Dear brothers and sisters, when we did not kown our Lord Jesus Christ, we did no thank Him, nor called upon His name. But now we know Him, the only true God, we should thank Him for all He does: He not only gave all his creation but also even He Himself to us: He died for our sins on the cross, and for our life He resurrects on the third day! Amen, Hallelujah! Now we not only glorify in your praise, O Lord, but we aslo need to call upon your name all the time, because you promised us that “And call upon me in the day of trouble: I will deliver thee, and thou shalt glorify me.” Amen! Hallelujah!
