Certainly the passages present the same basic truth..
Certainly, those that discern the truth are to pay attention to erroneous teaching which may deceive and hurt others. They contend for the faith, lest the deceived embrace error.
Key word, “soldier.”
The soldier in 2 Timothy 2 is a _________?
A. unbelieverNeither passage is written to or about the lost coming for salvation. They are as I stated above.
B. believer
That lack of discernment, often motivated by the desire to grasp something in a vain attempt to support what is not truth, is as bad as one thirsty thinking drinking ocean water is healthy.
Of course the passage addresses the lost becoming saved, for God does not desire any to perish, 2 Peter 3:9.
9 The Lord is not slow about His promise, as some count slowness, but is patient toward you, not wishing for any to perish but for all to come to repentance.
Here is the bottom line, we could cite each and every text used by Calvinism in support of the bogus TULI doctrines, and demonstrate the verse or passage is being misquoted or misrepresented as above.
