Well, from the research that I've done on this subject, it seems that there are two sides. One side focuses on Jesus' divinity while the other focuses on Jesus' humanity. I think I am one who focuses on Jesus' humanity.
I found it quite shocking when my friend said that Jesus did not have faith. From my perspective, the bible and Jesus himself speaks of us needing faith so often and so much in the bible, that it would seem very strange that he did not have faith, also.
In response to your message, the word for faith in
Habakkuk 2:4
4 "See, he is puffed up;
his desires are not upright—
but the righteous will live by his faith
is the same hebrew word used in Isaiah 11:5 to describe faithfulness.
5 Righteousness will be his belt
and faithfulness the sash around his waist.
(Edit: Habakkuk 2:4 is referenced in Galatians 3:11 and Romans 1:17 and the word faith (emuwnah) is translated as faith (pistis))
This is according to strong's concordance. Both faith and faithfulness come from the hebrew word emuwnah, meaning: firmness, fidelity, steadfastness, steadiness.
I've found that there are at least these many words used to render faith in the old testament: emuwnah, emeth, emuwn (5 uses), omen (used only once) and aman.
I'll show some more verses to hopefully demonstrate what it means to be faithful?
Numbers 12:7
7 But this is not true of my servant Moses;
he is faithful in all my house.
Faithful here is aman.
Deuteronomy 32:4
4 He is the Rock, his works are perfect,
and all his ways are just.
A faithful God who does no wrong,
upright and just is he.
Faithful here is from the hebrew word emuwnah.
Psalms 33:4
4 For the word of the LORD is right and true;
he is faithful in all he does.
Faithful here is emuwnah.
Psalms 36:5
5 Your love, O LORD, reaches to the heavens,
your faithfulness to the skies.
Faithfulness here is emuwnah.
Psalms 89:2
2 I will declare that your love stands firm forever,
that you established your faithfulness in heaven itself.
Faithfulness here is emuwnah.
Psalms 89:5
5 The heavens praise your wonders, O LORD,
your faithfulness too, in the assembly of the holy ones.
Faithfulness here is emuwnah.
Psalms 89:8
8 O LORD God Almighty, who is like you?
You are mighty, O LORD, and your faithfulness surrounds you.
Faithfulness here is emuwnah.
Isaiah 16:5
5 In love a throne will be established;
in faithfulness a man will sit on it—
one from the house [a] of David—
one who in judging seeks justice
and speeds the cause of righteousness.
Faithfulness here is emeth.
Isaiah 42:3
3 A bruised reed he will not break,
and a smoldering wick he will not snuff out.
In faithfulness he will bring forth justice;
Faithfulness here is emeth.
Isaiah 49:7
7 This is what the LORD says—
the Redeemer and Holy One of Israel—
to him who was despised and abhorred by the nation,
to the servant of rulers:
"Kings will see you and rise up,
princes will see and bow down,
because of the LORD, who is faithful,
the Holy One of Israel, who has chosen you."
Faithful here is aman.
I've tried to choose verses that show the quality of God. Hopefully this will show us what it means to faithful?
I know that faith (greek: pistis) as explained in the new testament is:
1Now faith is being sure of what we hope for and certain of what we do not see.
2This is what the ancients were commended for.
But the greek word pistis isn't found in the old testament. So, I guess I'm trying to show that faith has many aspects. One aspect is being sure of what we hope for and certain of what we do not see.
For now, the only evidence I have found in the greek to support my perspective is:
Revelation 2:10
10Do not be afraid of what you are about to suffer. I tell you, the devil will put some of you in prison to test you, and you will suffer persecution for ten days. Be faithful, even to the point of death, and I will give you the crown of life.
Faithful here is pistos.
Revelation 2:13
13I know where you live—where Satan has his throne. Yet you remain true to my name. You did not renounce your faith in me, even in the days of Antipas, my faithful witness, who was put to death in your city—where Satan lives.
Faithful here is pistos.
Revelation 3:14
14"To the angel of the church in Laodicea write:
These are the words of the Amen, the faithful and true witness, the ruler of God's creation.
Faithful here is pistos.
Revelation 17:14
14They will make war against the Lamb, but the Lamb will overcome them because he is Lord of lords and King of kings—and with him will be his called, chosen and faithful followers."
Faithful here is pistos.
Revelation 19:11.
11I saw heaven standing open and there before me was a white horse, whose rider is called Faithful and True. With justice he judges and makes war.
Faithful here is pistos.
I've tried to illustrate from the Revelation verses that Jesus is "faithful" (pistos) at least as much as he asks us to be "faithful" (pistos).
