Many claim to know God (or a "god") but do they really know Him---the Creator of heaven and earth? The Scriptures are plain in their teaching, yet too many have taken it upon themselves to alter their meaning, change the text to suit their fantasy god, or simply ignore the Scriptures all together. Most people say that all religions ultimately worship the same god whether Hindu, Muslim, Roman Catholic, or whatever flavor of man-made nonsense is presented as authentic "worship of God". Yet the Scriptures as found in the sixty six books of the Bible tell an entirely different story.
Today we find a new excuse for our sins: "we were born that way." But what does the Bible say that every person was born with, a proclivity and love for sin predisposing them to a life of uncontrollable rebellion (old sin nature), and a certain albeit limited knowledge of God? Rom. 1:19 & 20 gives the clear, unambiguous answer: a knowledge of God where we see His "invisible attributes" by the Creation. Going further we find this knowledge is expanded to include "even His eternal power and Godhead" or His being the only all powerful God (and as such, precludes even the existence of "other gods") who is totally sovereign and just and holy in all His actions toward the object of His will. But man, in his assumed wisdom, has decided to suppress this truth---that God is the Creator, the All-Powerful, the only and Sovereign God of all that is---Rom. 1:17. "Professing themselves to be wise, they became fools" (Rom. 1:22) and will suffer the consequences of their rebellion as God righteously 'gives them over' to the lust of their heart. So there are no "atheists", only those who through arrogant pride and a stubborn, deceitful heart claim to be one so as impress their fellow rebels.
Is this knowledge of God that all are born with sufficient for a man to attain eternal life? NO! If it were then all men would be "saved" simply by being born of a woman. The Scriptures say "You must be born again" John 3:3-8. This fact---the necessity of the second birth---is not found in any of the man-made religions and has been mutilated to the point of being unrecognizable in so-called "evangelical churches" the world over.
"I am the way, the truth, the life. No one comes to the Father except through Me." John 14:6. Yet EVERY man-made religion and most of the "evangelical" crowd of today go out of their way to circumvent these words of the Lord Jesus and offer "another way" (read "another gospel" as seen in Gal 1:6-9). The "evangelical other way" includes a simple mental ascent to the historical Jesus, a cursory (and meaningless) statement to the fact of their former sins, and an "acceptance of Jesus into their heart", none of which is mandated in the Scriptures (Mark 1:15 is clear). All of these little exercises are actually an insult to the Spirit of God, for it is His task to "convict the world of sin, and of righteousness, and of judgment" John 16:8 and He does not fail---ever! So did the 'repentance' you think you displayed "at the altar" produce anything in you but a smug self-satisfaction? The evidence of real God-wrought repentance is found in 2 Cor. 7:10 & 11. Is your former and present sin repugnant to you or do you still find pleasure in your sins? The most egregious, presumptive, and arrogant statement a man can make is to "invite Jesus into your heart." No such "command" is found, hinted at, or displayed in the Scriptures, but it's done thousands of times over. It is completely void of humility. It puts the one doing the "inviting" in a superior position to Almighty God (literally making man a "god"). It totally negates the necessity of grace on any level to be given a man. It puts the Lord in a position to be obliged to give what is demanded (again, no humility). It does away with gratitude to the Lord, because somehow they feel that He owes them "salvation", or whatever their demand may be. "Examine yourselves as to whether you are in the faith..." 2 Cor.13:5
Do you know God?
