“Truly, I tell you, with no one in Israel have I found such faith.

Matthew 8:8–10
8 But the centurion replied, “Lord, I am not worthy to have you come under my roof, but only say the word, and my servant will be healed. 9 For I too am a man under authority, with soldiers under me. And I say to one, ‘Go,’ and he goes, and to another, ‘Come,’ and he comes, and to my servant, 3 ‘Do this,’ and he does it.” 10 When Jesus heard this, he marveled and said to those who followed him, “Truly, I tell you, with no one in Israel 4 have I found such faith.

Who has?

Is there anyone in the Bible that has "operated in the fullness of God's guidence, provision and care"?...

YES! Jesus.

Has there been anyone in the Bible who has attempted to follow Jesus? Well Duh...

What an overcomer would say.

Philippians 3:12-16 (KJV)

12 Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus.

13 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,

14 I press toward the mark for the prize of the high calling of God in Christ Jesus.

15 Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.
