I am catholic by the way. I rarely quote scripture. That is partly because I don't have the knowledge of many good CF members who are raised on the Bible as the number one authority.
But I see my role in helping a fellow human being as first, being there for them. As an equal. Not as their scripture quoting superior. As if the OP's lack of knowledge of scripture is contributing to the problem.
See them first as fellow travellers. Don't condescend to them as if you are closer to Heaven , as if you have some special access to God's real intentions. Remember the importance of humility? Giving advice still requires humility. Didn't Jesus emphasise the value of humility?
It is very hard to go to others to show them the importance of humility and to emphasise the value of humility if you don't refer to the Biography of the Great Grandmaster of humility Jesus Christ.
After all what did the Holy Ghost lead Philip to do in the Acts of the Apostle?
Please read below and reflect......
Acts 8:26-40English Standard Version (ESV)
Philip and the Ethiopian Eunuch
26 Now an angel of the Lord said to Philip, “Rise and go toward the south[
a] to the road that goes down from Jerusalem to Gaza.” This is a desert place. 27 And he rose and went. And there was an Ethiopian, a eunuch, a court official of Candace, queen of the Ethiopians, who was in charge of all her treasure. He had come to Jerusalem to worship28 and was returning, seated in his chariot, and he was reading the prophet Isaiah. 29
And the Spirit said to Philip, “Go over and join this chariot.” 30 So Philip ran to him and heard him reading Isaiah the prophet and asked, “Do you understand what you are reading?”31 And he said, “How can I, unless someone guides me?” And he invited Philip to come up and sit with him. 32 Now the passage of the Scripture that he was reading was this:
“
Like a sheep he was led to the slaughter
and like a lamb before its shearer is silent,
so he opens not his mouth.
33 In his humiliation justice was denied him.
Who can describe his generation?
For his life is taken away from the earth.”
34 And the eunuch said to Philip, “About whom, I ask you, does the prophet say this, about himself or about someone else?” 35
Then Philip opened his mouth, and beginning with this Scripture he told him the good news about Jesus. 36 And as they were going along the road they came to some water, and the eunuch said, “See, here is water! What prevents me from being baptized?”[
b] 38 And he commanded the chariot to stop, and they both went down into the water, Philip and the eunuch, and he baptized him. 39 And when they came up out of the water, the Spirit of the Lord carried Philip away, and the eunuch saw him no more, and went on his way rejoicing. 40 But Philip found himself at Azotus, and as he passed through he preached the gospel to all the towns until he came to Caesarea.
You would be up against it if you think you can teach humility by your own solo efforts and solo works, if you don't have the biography of the King of humility and righteousness to refer to, to give evidence to your claim of humility. No different to making claims in essays by citing references as evidence. In fact all literary text, whether spoken or written need to be referenced and Philip in the Acts of the Apostle is a perfect example of the evidence on hand to refer to, to verify the act of humility, not our humility but Christ's humility through us as his witnesses.
To minister the gospel of Jesus Christ, you need to have his biography in your right hand and use it as your sole reference to your faith, otherwise who is to say that your claim of humility is verifiable and from what source it is.
Is your humility verifiable in Christ Jesus?
If so, show them his biography, give them scripture that testifies of the Great Grand Master of humility.
Say it ain't so Brother
