Note 4 at Acts 1:14: The fact that these disciples continued in one accord was a very important part of the whole miracle of Pentecost. The word used for "continued" here is the Greek word "proskartereo" which means "to be earnest towards, to persevere, be constantly diligent" (Strong).

They were able to avoid the divisions that customarily separate people because they had lost themselves in God. They were overwhelmed with the events of Jesus' resurrection to such a degree that selfish things were not important. Since pride is the cause of all contention (Prov. 13:10), ridding ourselves of pride is the only way that we will ever obtain unity.

Unity brings the blessing of God (Ps. 133) whereas strife brings the curse of the devil (Jas. 3:16). The power of God is always manifest every time believers come into unity (see note 3 at Jn. 13:35, p. 484).

Note 5 at Acts 1:14: These half-brothers of Jesus had rejected Jesus as the Messiah before His crucifixion (see note 2 at Jn. 2:12, p. 88). The scriptures don't tell us exactly when they became believers, but it is very clear in this passage that they were among those who were waiting for the coming of the Holy Ghost. One of these brothers went on to become the head of the Jerusalem church (see note 2 at Jn. 2:12, p. 88).
