Jesus is saying He will give us comfort (John 14:26) and the peace that surpasses all understanding (Philippians 4:7 ) while dealing with life’s trials and tribulations, which only get worse when you try to walk the straight and narrow path…
There are countless examples of this in scripture and Church history. One that your protestant friends can acknowledge with SS mentality is Stephen, who was martyred for the Lord :
54 When the members of the Sanhedrin heard this, they were furious and gnashed their teeth at him. 55 But Stephen, full of the Holy Spirit, looked up to heaven and saw the glory of God, and Jesus standing at the right hand of God. 56 “Look,” he said, “I see heaven open and the Son of Man standing at the right hand of God.”
57 At this they covered their ears and, yelling at the top of their voices, they all rushed at him, 58 dragged him out of the city and began to stone him. Meanwhile, the witnesses laid their coats at the feet of a young man named Saul.
59 While they were stoning him, Stephen prayed, “Lord Jesus, receive my spirit.” 60 Then he fell on his knees and cried out, “Lord, do not hold this sin against them.” When he had said this, he fell asleep.
Look how comforted Stephen was in his moment of suffering.
Another example they can look to is Paul. who said he gladly BOASTS in his afflictions
2 Corinthians 12:5-10New International Version (NIV)
5 I will boast about a man like that, but I will not boast about myself, except about my weaknesses. 6 Even if I should choose to boast, I would not be a fool, because I would be speaking the truth. But I refrain, so no one will think more of me than is warranted by what I do or say, 7 or because of these surpassingly great revelations. Therefore, in order to keep me from becoming conceited, I was given a thorn in my flesh, a messenger of Satan, to torment me. 8 Three times I pleaded with the Lord to take it away from me. 9 But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me. 10 That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.
In addition to his “thorn in the flesh”, Paul was also imprisoned for the Lord
And Jesus chastises those who he loves:
6 because the Lord disciplines the one he loves,
and he chastens everyone he accepts as his son
As many as I love, I rebuke and chasten: be zealous therefore, and repent.
And on and on and on we go with sufferings in the Church. Faithful or not, we all suffer.
11 of the 12 apostles martyred for the faith…many Popes martyred for the faith.
Those who teach a Gospel w/o suffering are only fooling themselves.
Read the beatitudes how it talks about the importance of humility in your walk with Christ. But how does one become humble ?Through HUMILIATIONS or suffering.
