Others say, if you DON'T follow god, then you are an error-slave.
I say, if you are an error-slave, how can you be expected to identify "the truth"?????????????????????
It becomes willy nilly, doesn't it, if you have no fixed and absolute reference point?
Your hypothetical god must be a moron if they expect error-slaves to be able to figure out which religion is "the right one".
Now you are using ad hominem implications for what would it say about those who believe in this God? Are they morons too?
Can you show me that you are not a slave to those desires that control you? I contend we are all slaves to something if you want to use the slave analogy. It is by the grace of God, His mercy, and His revelation that we come to the truth. Take that statement however you want.
How is anyone supposed to know?
Romans 1:18-26 (NASB)
Unbelief and Its Consequences
18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness, 19 because that which is known about God is evident within them; for God made it evident to them. 20 For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse. 21 For even though they knew God, they did not honor Him as God or give thanks, but they became futile in their speculations, and their foolish heart was darkened. 22 Professing to be wise, they became fools, 23 and exchanged the glory of the incorruptible God for an image in the form of corruptible man and of birds and four-footed animals and crawling creatures.
24 Therefore God gave them over in the lusts of their hearts to impurity, so that their bodies would be dishonored among them. 25 For they exchanged the truth of God for a lie, and worshiped and served the creature rather than the Creator, who is blessed forever. Amen.
The biblical God has revealed Himself to humanity. What you do with that revelation is between you and God. The boldened/underlined section above reveals as much.
I can lie it out for you further.
1. You know God exists yet you suppress the truth of God with your unrighteousness.
2. God has supplied the evidence of Himself with each human being.
3. It is by hardening our hearts to God and denying Him that suppresses the truth of God.
4. His divine nature is seen in what has been made.
5. Thus, you are without excuse.
Now, if you want to know God you first have to believe He exists instead of suppressing this biblical truth.
Hebrews 11:6 (NASB)
6 And without faith it is impossible to please Him, for he who comes to God must believe that He is and that He is a rewarder of those who seek Him.
To think you will know God when you deny His existence is illogical. Yet if you truly seek Him I truly believe He will be found by you. And it has to be the one and only true God. Will your own mind get in your way? Will you adamantly reject Him or call out to Him? Again, that is between you and God.
