Was Jesus being melodramatic when He stated that He didn't even have a place to lay His head? Was He expressing spiritual superiority or a sanctimonious nature?
That's non-sequitor, meaning, an invalid argument. It's like saying, No, Airplanes cannot fly because brocolli.
Jesus was stating truth, just like God always tells us the truth.
The REAL humility is walking together in peace.
Ephesians 4:2-3 KJV
2) With all lowliness and meekness, with longsuffering, forbearing one another in love;
3) Endeavouring to keep the unity of the Spirit in the bond of peace.
Its a false spiritual superiority that says, I shall not stoop down to walk in harmony with others!!
Ephesians 4:11-17 KJV
11) And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;
12) For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
13) Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:
14) That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;
15) But speaking the truth in love, may grow up into him in all things, which is the head, even Christ:
16) From whom the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love.
17) This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk, in the vanity of their mind,
I'd suggest you spend the time, a month or two, to REALLY learn Ephesians 4. We are to be in fellowship with each other because it is God's given means by which we are nourished. By each other. This "walking alone" stuff is not Biblical.
Much love!
