“The kingdom of heaven is like a landowner who went out early in the morning to hire laborers for his vineyard.” (v. 1)
This parable, recorded only by Matthew, is closely connected with the end of the nineteenth chapter and Peter's question as to how it should fare with those who, like himself, had left all for Christ.
This teaching is designed to show that while the disciples would be richly rewarded, a certain equity would still be observed towards later converts and workmen in His service who may not have labored as long. While some men may have come to Christ earlier in life, and served Him longer than others who have been recently converted, all believers will enter the kingdom of heaven.
Thus, every man ought to go forward in service to Him without stopping or staggering, and not curiously examining the doings of other men. The lesson here is, watch out for jealousy and greed. Be more concerned with answering your calling, not your position or reward through it.
The Truth: “By faith Abraham obeyed when he was called to go out to the place which he would receive as an inheritance. And he went out, not knowing where he was going.” (Hebrews 11:8)
