[8] For illustration of what is here said, Matt. xxi. 16 may be compared with Psalm viii. 2, Acts xv. 15-17 with Amos ix. 11, 12, and Eph. iv. 8 with Psalm lxviii. 18; and the list might be largely increased.
[9] Hence the New Testament writers quote from the LXX. in a very large proportion. The writer of the Epistle to the Hebrews quotes nothing else.
But "shall not be ashamed" was a form of the promise more suited to the days of St. Peter and these infant Churches. For the name of Christ was in many ways made a reproach; and only men of faith, like Moses and the heroes celebrated with him in Heb. xi., could count that reproach greater riches than the treasures of Egypt. Other and weaker hearts needed encouragement, needed to be pointed to the privileges and glories which are the inheritance of the followers of Jesus. And in this spirit he applies the prophetic words, _For you therefore which believe is the preciousness_. Faith makes real all the offers of the Gospel. It opens heaven, as to the vision of St. Stephen, so that while they are still here believers behold the glory of God to which Christ has been exalted, are assured of the victory which has been won for them, and that in His strength they may conquer also. Thus they receive continually the earnest of those precious and exceeding great promises (2 Peter i. 4) whereby they become partakers of the Divine nature.
But all men have not faith. The Bible tells us this on every page. God knows what is in man, and in His revelation He has set forth not only invitations and blessings, but warnings and penalties. Life and good, death and evil--these have been continually proclaimed as linked together by God's law, but ever with the exhortation, "Choose life." Of such warning messages St. Peter gives examples from prophecy and psalm: _But for such as disbelieve, the stone which the builders rejected, the same was made the head of the corner_ (Psalm cxviii. 22), _and a stone of stumbling and a rock of offence_ (Isa. viii. 14); _for they stumble at the word, being disobedient_. Here the Apostle touches the root of the evil. The test of faith is obedience. It was so in Eden; it must be ever so. But now, as then, the tempter comes with his insidious questionings, "Hath God said?" and sowing doubts, he goes his way, leaving them to work; and work they do. Now it is the truth, now the wisdom, of the command, that men stumble at. But in each case they disobey. Those leave it unobserved; these despise and set it at nought. And the penalty is sure. For mark the twofold aspect of God's dealing which is set forth in the passages chosen by St. Peter to enforce his lesson. Spite of man's disobedience, God's purpose is not thwarted. The stone which He laid in Zion has been made the head of the corner. Though rejected by some builders, it has lost none of its preciousness, none of its strength. Those who draw near unto it find life thereby; are made fit for their places in the Divine building, in the kingdom of the Lord's house which He will most surely establish as the latter days draw on. But they who disobey are overthrown. The despised stone, which is the sure word of God, rises up in men's self-chosen path, and makes them fall, and at the last, if they persist in despising it, will appear for their condemnation.
_Whereunto also they were appointed._ The Apostle has in mind the words of Isaiah, how the prophet, in that place from which he has just quoted, declares that many shall stumble and fall, and be broken, and be snared, and be taken. This is the lot of the disobedient. These penalties dog that sin. It is the unvarying law of God. The Bible teaches this from first to last, by precepts as well as by examples. The disobedient must stumble. But the Bible does not teach that any were appointed unto disobedience. Such fatalist lessons are alien to God's infinite love. The two ways are set before all men. God tries us thus because He has gifted us above the rest of creation, that we may render Him a willing service. But neither prophet nor Apostle teaches that to stumble is to be finally cast away. Both picture God's mercy in as large terms as those in which St. Paul speaks of the Jews: "Did God cast off His people? God forbid.... They, if they continue not in their unbelief, shall be grafted in, for God is able to graft them in again" (Rom. xi.).
