This journey we're on leads to removable things being shaken out. Only the unshakeable kingdom would remain (12:26–29). The promises of old were emerging as Jerusalem's demise came nearer. The ancient city being removed from before God (as it were) so the promised City, designed and built by God, the New Jerusalem, could rise & stand.
What Abraham yearned for and "saw" with his eye of faith, was on the cusp of coming true. The faith he demonstrated through hard choices was exactly what HW's audience needed. They were on the verge of the "great tribulation." It would shake away the chaff. Only the wheat would remain (Matt.3:12; Mal. 4:1–2). They needed this focus to stay the course. Conduct critical to success is always found in yesterday's heroes.
Abraham was willing to sacrifice a son to stay with God. Joseph knew he would be leaving Egypt. "Take me with you when you go," he said to God's people. Moses, for all his position and power, gave it all up to have what these people were about to receive.
These all made conscious, considered decisions. Sacrifice comes from mindful pondering. Faith is the product of reflection; but it leads to decision and action. So it was with Moses. So it was with this generation. So it is with us!
Be sure to join us. We're looking at choices that change the course of life—Hebrews 11.
