Thank you all for your insightful responses. They get me thinking. I too considered the giants in Caanan. These were mighty giants indeed! They were so tall that in comparison humans were the size of grasshoppers.
But were these giants truly that big? Why did these "giants" have such a profound effect on the Israelites that they didn't even want to enter the Promised Land? Obviously the people had exagerated the size of the giants. But not everyone saw them so ominously large. Why did Caleb and Joshua have a different perspective?
I think there actually were bigger and taller people and this illustrates how men look on the outward and walk by sight and not faith (in God's promises).
A wee note on the word "self". I recall Ron Bailey recently challenging our use of that word. He noted that you don't see this use of the word in scripture. Interestingly as I read through Hudson Taylor's material I don't see the word either. But I would agree that there is something about ourselves that is indeed a potential giant - as you have noted!
That is true, "self" was never a word that stood alone or was used alone in those days. It was always connected to someone's attitudes, actions or speech and was not an independent concept.
Mar 8:34 And when he had called the people unto him with his disciples also, he said unto them, Whosoever will come after me, let him deny HIMSELF, and take up his cross, and follow me.
To understand what it means to "deny ourselves" it requires the awareness and admission of our selfish tendencies patterned in the "flesh". And it does not refer to a subjective, psychological denial, but a volitional denial whereby we choose to disallow the expressions of selfishness in our behavior.
Titus 2:12 - "deny ungodliness and worldly desires"
Phil. 2:3,4 - "do nothing from selfishness...do not look our for your own personal interests..."
Denying ourselves is not a "work" of self-effort and performance whereby we overcome and get rid of the "flesh"
Gal. 5:17. Such is a denial of God's grace.
Gal 5:17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
Gal 5:18 But if ye be led of the Spirit, ye are not under the law.
Then, Paul goes on to talk about the works of the flesh and the fruit of the Spirit and then...
Gal 5:24 And they that are Christ's have crucified the flesh with the affections and lusts.
Denying ourselves is part of the process of sanctification.
But the biggest problem that we all contend with is UNBELIEF.
Heb 3:12 Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.
It is always unbelief that will keep us from entering into God's promises.
Heb 3:19 So we see that they could not enter in because of unbelief.
Heb 4:6 Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:
Heb 4:11 Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.
