@PeterC’s wise application of the Hebrews passage is just the medicine suitable for the present ailment (IMHO).
@JennyLynne, you answered your own question(s) clearly when you said:
Personally, in my life I shorten your statement to say, “Walking by Faith is taking God at His word”.
We all experience two voices vying for our submission. It is not uncommon that the Word of God states something emphatically that our society either questions, dismisses altogether, or strongly opposes. These two voices confront us with personal decisions at every one of life’s junctures. We all have natural (innate) instincts to gather immediate data, listen to the counsel of others, interpret our surroundings, imagine outcomes, and then choose a path to move forward. The promise Jesus made to his disciples was that The Holy Spirit would guide them (paraclete) in these efforts as they waited for His return. For you and I, The Holy Spirit does most of this guiding through the printed Word of God; a precious gift, a second witness in harmony with the indwelling Spirit, to teach us how to make these daily decisions. The two Heavenly witnesses, The indwelling Holy Spirit, and the written Word of God, are always in perfect agreement, they are always one unified voice; one emphatic leading. Quite simply, a disciple can have none of one without a fullness of the other. So, walking “in the Spirit” is walking “In the Word” and visa-versa. There is no walking in The Spirit without walking in The Word, and visa-versa.
This is the state we find ourselves in, for the moment, subjected to these two voices, the untrustworthy voice of this world, and the True Voice, which speaks from the next. The internal witness of God causes us to yearn to put off the earthly cloak, and put on our eternal dwelling; a place of one voice, speaking in perfect peace, and testifying of the fullness of our Savior. Then we will know, just as we are known. But until then, we walk by faith, and not by sight.
For we know that if our earthly house, this tent, is destroyed, we have a building from God, a house not made with hands, eternal in the heavens. For in this we groan, earnestly desiring to be clothed with our habitation which is from heaven, if indeed, having been clothed, we shall not be found naked.
For we who are in this tent groan, being burdened, not because we want to be unclothed, but further clothed, that mortality may be swallowed up by life. Now He who has prepared us for this very thing is God, who also has given us the Spirit as a guarantee. So we are always confident, knowing that while we are at home in the body we are absent from the Lord. For we walk by faith, not by sight.
We are confident, yes, well pleased rather to be absent from the body and to be present with the Lord. Therefore we make it our aim, whether present or absent, to be well pleasing to Him. For we must all appear before the judgment seat of Christ, that each one may receive the things done in the body, according to what he has done, whether good or bad. Knowing, therefore, the terror of the Lord, we persuade men; but we are well known to God, and I also trust are well known in your consciences. (2 Corinthians 5:1-11)
Waiting in anticipation with you.
