"All Scripture is inspired by God
and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work." 2 Timothy 3:16-17
Please explain how a deficient work can make one "adequate" in the eyes of a perfect God who demands only perfection?
Scripture is enough.
You make the classic mistake of not reading what the verse says, but rather what you wish it would say.
All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work."
Scripture being "profitable" (some say "useful") does not make it sufficient. That it is an indispensible item to "adequately" (some say "perfectly") equip a man does not mean it is sufficient for the task.
Observe:
All gasoline is refined by oil companies and is profitable for combustion, so that the modern motorist can be adequatelly equipped for long distance travel.
Does this mean that gasoline is all one needs for travel? Of coruse not. One needs a car, tires, brakes, provisions, a map, etc. You have employed the classic "Cuba Libre" defense. Limes are profitable for fully equipping a Cuba Libre, but I would not want to drink one made solely of limes.
