Christ says otherwise.
According to you. Then there's St. Peter and the crowing cock.
No, we cannot look at another's life and say, "if that happened to me, I wouldn't..."
We don't know what our trials will be and whether we will pass them or fail, until we do.
Only God knows. Only He is the judge of our trials.
Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
Wow. So much for assurance of Christ's faithfulness in the RCC.
Of course we don't know what trials are ahead of us. But with God's grace through faith in Christ, we can be sure God will bring nothing to us that will overcome us. With Him, all things are possible.
"There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it." -- 1 Corinthians 10:13
Why is Christ so confident in John 16:33 when He tells us the world is filled with tribulations, but that we shouldn't worry?
Because He has overcome the world. He is certain of His righteousness and He knows whom God has covered in that righteousness -- those who believe.
Therefore, our confidence that we will surmount the hills and pass through the valleys is not based on our strength, righteousness or obedience, but on Christ's strength, righteousness and obedience, mercifully imputed to us. Rome just doesn't believe Him.
"But the Lord is faithful, who shall stablish you, and keep you from evil." -- 2 Thess. 3:3
Christ will either "keep us from evil," or He won't.
Further, when Christ tells us to be careful how we judge, He is not telling us not to discern right from wrong. Three verses later He says, "first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye."
So Christ is saying to know the truth before we speak the truth to someone else.
Because consider what Jesus says in John 7...
"Judge not according to the appearance, but judge righteous judgment." -- John 7:24
Jesus is instructing men to judge according to His word.
He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water." -- John 7:37-38 "In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink.
Drink not His literal blood, but the "living waters" of the Holy Spirit, as Scripture tells us.
“We do not know what our trials will be and whether we will pass them or fail, until we do”.
Interesting that you should write this just as I was reading these words of the newly-Blessed John Henry Cardinal Newman:
“We can never answer how we will act under new circumstances. A very little knowledge of life and of our hearts will teach us this.”
