Which is simply another false dichotomy. Just where do you get your definition of your Jesus? Did He personally appear to you? Why do you even believe in the Nicene Creed?
Which argument employs another logical fallacy a well as an error of ignorance. As regards the former, the fact that someone is given the word of God, but does not apprehend it, simply does not impugn at the least the necessity and efficacy of it. One can have access life-saving medicine, but unless they take it then they can die.
As regards your factual error, the Jews who Jews memorized the entire Law did believe in God, (Acts 26:7) as even demons do, but not unto salvation, since they do not believe all He said. Of course, if one rejects Scripture, then they can just dismiss what it says about anyone.
And the soothsayer Joseph Smith also claimed to see Jesus, the Father and the Son, as well as converse with Moses, Elias and Elijah. The point is that visions alone are not determintive of what is valid, and while some people in the past as well as the present can believe on the Lord Jesus via a dream or vision, such subjective experiences are subject to testing by the established authority, which the Christ of Scripture attested to.
The fact is that apart from Scripture, the Christ you believe in could be anything or anyone.
But which is also a false either/or dichotomy, for the fact that faith is given to us from God is simply not opposed to faith coming from the word of God, and of Scripture assuredly being the word of God. God also gives food, however, He usually uses a delivery service of types.
Who said anything about being earned? That is simply a strawman which flows from your previous false either/or dichotomy.
Which contradicts your previous statement on the Bible, "I know we don't need it." Now it is true that God could even appear in the clouds to every nation and declare, "I am God almighty, and I am going to show you how I want things to be done from now on," and zap Hollywood studios (among other things and people).
However, this is not anything like how God works as a norm (but remember Sodom).
For
while God expressly revealed Himself to a very limited few and His will in a very limited scope, yet when He chose to reveal His will to an entire nation then He preserved it in writing, which is His manifest means of preservation. (Exodus 17:14; 34:1,27; Deuteronomy 10:4; 17:18; 27:3; 31:24; Joshua 1:8; 2 Chronicles 34:15,18-19; Ps. 19:7-11; 119; John 20:31; Acts 17:11; Revelation 1:1; 20:12, 15;Matthew 4:5-7; 22:29; Lk. 24:44,45; Acts 17:11)
And as is abundantly evidenced, the "word of God/the Lord" was normally written, even if subsequent to to being spoken, and as written, Scripture became the transcendent supreme substantive standard for obedience and testing and establishing truth claims as the wholly Divinely inspired and assured, Word of God.
Indeed. However, the ones who preached to them were those to whom the Lord, "beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself." "that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me. Then opened he their understanding, that they might understand the scriptures." (Luke 24:44-45) (Luke 24:27)
And thus the Christ they believed in was not some abstract deity, but one whose message of His identity and work flowed out of Scripture, and thus the Gentiles converts were immediately schooled in Scripture as able, "Which he had promised afore by his prophets in the holy scriptures," (Romans 1:2) "But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith." (Romans 16:26)
They are not simply personal testimonies about Jesus in their lives, but also of public declarations about Himself and His will, preserved by inspired-of-God writing, and as such the transcendent supreme substantive standard for obedience and testing and establishing truth claims.
In contrast, you are elevating subjective experiences of God above the objective established supreme transcendent substantive testimony of Scripture, to which the Christ of Scripture appealed to as being so. The former certainly is indispensable, for Scripture promises it, but they are not the supreme standard on Truth.
