Define "sufficient". I, on the other hand, am certain, by virtue of God's grace, that Jesus is who he claimed to be and who scripture, generally, portrays him to be.
You have chapter and verse for what I bolded in red?
Actually, I have a lot:
An issue frequently cited as a stumbling-blocks to belief in the NT God for some people
is reconciling God’s power and love with the fact of evil and its consequence. A person—even a theist—might think that God would not permit evil, suffering and hell to exist. People who are mystified by evil and repulsed by its punishment do not realize that the essential aspect of being a human rather than a robot or subhuman creature is moral free will (MFW), which is what enables a person to experience love and meaning. This is what makes humans different from animals, whose behavior is governed mainly by instinct. This is what it means to be created in God’s image (GN 1:26-27; robot or responsible)?
God could not force people to return His love without abrogating their humanity. If God were to zap ungodly souls, it would be tantamount to forcing conversions at gunpoint, which would not be free and genuine.
If God were to prevent people from behaving hatefully, then He would need to prevent them from thinking evilly, which would make human souls programmed automatons. Even if God were to prove Himself to skeptics by means of a miracle, they might believe for awhile and then as their memories began to fade they would probably think that God had died and revert to their former doubt—necessitating an endless string of miracles (recapitulating the story of the Israelites on the way to Canaan after the exodus from Egypt).
However, for reasons we may understand only sufficiently rather than completely,
God designed reality so that experiencing His presence is less than compelling, so that even Jesus (God the Son) on the cross cried out “My God [the Father], why have you forsaken [taken God the Spirit from] me?” (MT 27:46, PS 51:11) This phenomenon is sometimes called “distanciation”, because we experience God as distant from us and “unknown” (ACTS 17:23), even though He is close or immanent, “for in Him we live and move and have our being” (ACTS 17:28). Distanciation is not forsaken.
MFW only exists when there is the possibility of choosing between two qualitatively opposite moral options that we call good and evil. These options are opposites because of essentially different consequences for choosing them. Choosing good results in blessing, life and heaven; and choosing evil results in cursing, death and hell (DT 30:19). This is why hell as well as heaven exists. It is the just consequence for choosing evil rather than God. The Spirit of God is good: love, peace and joy (GL 5:22-23). Therefore, whoever rejects the Lord is spiritually separated from Him (IS 59:2) and thereby chooses the evil or satanic spirit of hatred, strife and misery and reaps the just consequence called “hell” in the afterlife (GL 6:7-9, HB 9:27-28). These options were presented by Moses to the Israelites (DT 30:19), and Jesus referred to this fundamental choice in terms of a fish or egg versus a snake or scorpion (LK 11:11-13). Life… or Curse? (GN 3:24, RV 22:1-2)
God created theoretical evil or the possibility of rejecting Him as an option that actualizes free human personality. As such it is necessary and even good (GN 1:31). Of course, it was wrong for Satan (1JN 3:8) and humanity (RM 5:12) to make evil actual by choosing to Sin or reject Faith in God’s Lordship. Sin: ignoring God/God’s Word. God loves a cheerful giver (2CR 9:7), which means He desires people to cooperate with Him happily because of love and gratitude for His grace rather than to cower before Him because of fear of hell. Love must be evoked; it cannot be coerced. And again, when souls sin or do NOT choose to love God freely, it is perfectly just (loving and logical) for them to reap the appropriate consequence (GL 6:7-9) or hell.
