Acts 1:12-26 covers a brief waiting period (about one week) between the ascension of Christ and the outpouring of the Holy Spirit on the day of Pentecost. The things that are recorded here were written by Luke, by divine inspiration, for our learning and admonition. If we are wise, we will lay them to heart.

First, THE LORD JESUS CHRIST FULFILLED EVERY PROPHECY OF THE OLD TESTAMENT SCRIPTURES RELATING TO HIS INCARNATION, LIFE, EARTHLY MINISTRY, CRUCIFIXION, RESURRECTION, AND ASCENSION (v. 12). When Luke tells us that the disciples returned from the mount called Olivet to Jerusalem, he is, almost casually, telling us that Christ stood upon Mt. Olivet when he ascended to heaven, just like the prophet Zechariah said he would (Zech. 14:4; Ezek. 11:23). The mount had been divided in two parts by a great earthquake in the days of Uzziah. Our Lord ascended from that part of it which was near Bethany (Luke 24:50). It was there that he began his sufferings (Luke 22:39). It was most fitting therefore that he should cast off the reproach of his sufferings there by his glorious ascension.

Second, THE PATH OF BLESSEDNESS AND USEFULNESS IS THE PATH OF OBEDIENCE (vv. 12-14). The disciples returned to Jerusalem because the Lord commanded them to do so (v. 4). There their enemies awaited them. There they were most likely to suffer and be persecuted. But the Lord's commandment was clear. So they returned (Prov. 3:5-6). There in a large upper room, they met together in prayer, united in heart, waiting for the promise of the Holy Spirit. Much needed to be done. They had a message to proclaim. Sinners were perishing. But the Lord had commanded them to wait. So they waited. They were waiting upon the Lord, waiting for God to move, waiting for God to come upon them, waiting for God to open the door before them (Psa. 27:15; 62:5-7; Chron. 15:13). We must obey his Word and wait for his direction. In all things, the point of our responsibility is the commandment of God. We must obey him. Obeying his Word, the disciples were filled with the Spirit and greatly used of God for much good.

Thirdly, EVEN THE BEST OF MEN ARE ONLY MEN AT BEST(vv. 15-26). So long as we are in this world we will be prone to error and sin. We stray in many ways and err in many things. Even true, faithful servants of God are weak, fallible men of flesh and blood. This is manifest in the fact that Peter led the disciples to choose an apostle God had not chosen.

Without question, Peter was a faithful man. He had the heart of a true pastor. On other occasions he acted rashly from bad motives, but not here. His motives were good. He wanted what was best for the glory of God, the people of God, and the gospel of God. The sin of Judas had made a vacancy in the apostolic office. Twelve apostles were originally chosen and ordained. As there were twelve tribes in Israel, descended from the twelve patriarchs, so there were twelve apostles. They are the twelve stars which make up the church's crown (Rev. 12:1). For them, twelve thrones were reserved (Matt. 19:28). Peter read Psalm 69:25 and concluded that it was the responsibility of the church to fill the vacancy left by Judas' apostasy. His error was an error of judgment, not of motive or principle.

He humbly recognized the sovereignty of God in all that had happened (v. 16). He understood that the death of Christ was the work of God for the redemption of his people (Acts 2:23; 4:27-28). He realized that God had sovereignly overruled the evil deeds of Judas to accomplish his own eternal purpose (Psa. 41:9).

Peter sorrowfully remembered the fall of his former friend and companion (v. 17-19). He said no more about the subject than was necessary. Though he and Judas had been close friends, he bowed to the will of God and honored the judgment of God upon his friend. Peter knew that the only difference between him and Judas was the grace of God (I Cor. 4:7).

He reverenced and honored the Word of God (v. 20). Peter sincerely wanted to obey the Scriptures. He thought he was doing what God would have him do. He was motivated by an earnest desire for the glory of God. With genuine reverence, he sought the will of God (vv. 21-25).

Peter should have sought the Lord before he appointed Justus and Matthias. Never say to God, "Lord, I am going to do this or that, you choose which you want me to do." Rather, go to God and say, "What will you have me to do?"

When the lots were cast, Peter led the church to ordain an apostle God had not chosen (v. 26). It was true, the Lord's intention was for his church to have twelve apostles, twelve and only twelve. David's prophecy must be fulfilled. Another apostle must take Judas' place. But, like the others, he must be personally chosen and ordained to the office by Christ himself. The Lord had not chosen Justus or Matthias for this office. He had chosen Paul (I Cor. 15:8).

How could Peter have made such a mistake? He sought to determine the will of God by casting lots. Like David, he made the mistake of seeking to determine the will of God by seeking the will of the people (I Chron. 13:1-4). He tried to accomplish the will and work of God by the wisdom and energy of the flesh! As a result, Matthias was chosen to do what God had not gifted him to do. So far as we know, he never preached a sermon or wrote an epistle. We can only speculate about what became of him. But his name is never mentioned again. Where God ordained twelve apostles there was neither room nor need for thirteen!

Still, Peter was God's appointed leader for that early church. In spite of his many errors, faults, and falls, Peter was God's man, and the people of God rightfully submitted to his rule as their pastor (Heb. 13:7, 17). Though he was a fallible man, he was a faithful man. He preached the gospel of Christ, sought the will of God, lived for the glory of God, and served the people of God. Blessed is that congregation who has been given such a pastor after God's own heart (Jer. 3:15). Faithful pastors do sin. Faithful pastors do err in judgment. Faithful pastors do even err in doctrine. Faithful pastors do make mistakes. Faithful pastors need the prayers and the love of God's people (I Thess. 5:12, 13, 25; Heb. 13:18).
