If you don't believe Paul, you don't believe Peter's testimony concerning Paul's writings.... if you don't believe Paul or Peter, why believe any of the writers? if they were liars, why would you believe they wrote the truth of "what Jesus said"... ?
You would not know what parts to believe and what not to believe… this is false teaching saying that God’s word can not be trusted…
2 Timothy 3:16-17: "16 All Scripture
is given by inspiration of God, and
is profitable for doctrine, for reproof, for correction, for instruction in righteousness, 17 that the man of God may be complete, thoroughly equipped for every good work."
The Epistles of Paul are included in the "all Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work" (2 Timothy 3:16-17). It has been affirmed in Scripture, God directly inspired what has been written in His Word (1 Corinthians 2:12-13; 2 Timothy 3:16-17; 2 Peter 1:21) and He preserves His Word (Psalms 12:6-7; Psalms 33:11; Psalms 100:5; Psalms 111:7-8; Psalms 117:2; Psalms 119:89-90, 152, 160; Isaiah 40:8; 1 Peter 1:23), as the prophet Isaiah described, "from henceforth and forever" (Isaiah 59:21). In fact, His Word is alive and sharper than any two-edged sword (Hebrews 4:12-13). It has been affirmed in Scripture that every word He speaks is pure (Proverbs 30:5-6), perfect (Psalms 18:30; Psalms 19:7), absolute truth (Psalms 119:16), and eternal (Psalms 119:89). The entirety of His word is truth (Psalms 119:16) and everlasting (Proverbs 8:23), being settled in heaven (Psalms 119:189), it stands forever (Isaiah 40:8; 1 Peter 1:25), and will not return to Him in void (Isaiah 55:11). His counsel and His righteous judgments stand forever (Psalms 33:11; Psalms 119:16).
He is the living God and the everlasting King (Jeremiah 10:10), from everlasting to everlasting, He is God (Deuteronomy 33:27; Psalm 90:2; 1 Timothy 1:17), and there is no shadow of turning with Him (James 1:17).
He does not change (Malachi 3:6; James 1:17)
nor does He lie (Numbers 23:19; 1 Samuel 15:29). He is
perfect (Psalms 18:30; Matthew 5:48) and so is His Word (Psalms 18:30; Psalms 19:7). He is referred to in His Word as an all consuming fire (Isaiah 6:3; Habakkuk 1:13; Exodus 3:2, 4-5; Hebrews 12:29),
infinite (Deuteronomy 33:27; Psalm 90:2; 1 Timothy 1:17),
unchanging (Malachi 3:6; Numbers 23:19; Psalm 102:26, 27),
incomparable (2 Samuel 7:22; Psalm 86:8; Isaiah 40:25; Matthew 5:48),
unfathomable (Isaiah 40:28; Psalm 145:3; Romans 11:33, 34),
incorruptible (Psalm 117:2; 1 Samuel 15:29), and
unequaled (2 Samuel 7:22; Isaiah 40:25). He is
omnipotent (Revelation 19:6; Jeremiah 32:17, 27),
omnipresent (Psalm 139:7-13; Jeremiah 23:23), and
omniscient (Psalm 139:1-5; Proverbs 5:21; 1 John 3:20).
He is also just (Acts 17:31),
loving (Ephesians 2:4-5),
truthful (John 14:6),
holy (1 John 1:5),
merciful (Romans 9:15),
full of grace and compassion (Romans 5:17; 2 Corinthians 1:3). He offers forgiveness through His Son Jesus Christ(Psalm 130:4; Isaiah 53:4-6; John 15:15; Acts 4:12; Romans 5:10; Ephesians 1:7; Ephesians 2:8-9; Titus 3:5; 2 Timothy 2:10). And He promises to be found by those who seek after Him with all their heart (Jeremiah 29:13) and have faith in Him (Hebrews 11:6).
If a professing Christian does not believe and fully trust in what God has had written in the Scriptures (which within themselves make the claim that ALL scripture is God-breathed) than how can they believe and fully trust in God for their own salvation?I cannot help but wonder if these same professing Christians think God lied or He was somehow mistaken when He said that ALL Scripture is given by His inspiration, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work. I personally believe that God's Word is the sole authority for the Christian faith and practice. If I don't believe what someone has told me, it is because I don't trust them enough to take them at their word. Such a person has not earned my trust or my devotion. However, this is not the case when it concerns my Heavenly Father.
