In John 10:35, Jesus makes a parenthetical statement that is easy to overlook, and yet it is a foundational principle when it comes to understanding the Bible. He says, “. . . and the Scripture cannot be broken. . .” (emphasis ours throughout).
The written Word of God is another part of His creative work, and in His inspired words, we see the same forethought, consistency, and magnificence that we see in everything that God does. Because His character is true and constant, the Scriptures can never be contradictory. When we encounter something in them that seems incongruous, the defect is only in our understanding, not in what God has provided for us.
The religious tradition that took root and gained prominence after the deaths of the first-century apostles did not hold this principle inviolate, and as a result, nominal Christianity today holds doctrines that are an unholy mixture of portions of the Scripture, along with pagan beliefs and philosophies that have been picked up through the millennia. In contrast, true doctrines fit together in a unified whole, each one supporting and reinforcing the overall body of beliefs. Because of this, if one doctrine is changed or misapplied, the consistency of the whole begins to unravel.
A clear example of this is what the Bible steadfastly shows regarding God's calling and election. Scripture teaches that a man cannot even approach the Messiah unless the Father draws, or calls, him (John 6:44). In other words, salvation is not available to all people right now. But because not all professing Christians truly hold to the inerrancy of God's Word, many believe that anyone can accept Jesus Christ as his Savior, and all that is needed is for other Christians to win over the unsaved. Sometimes this belief is pure and altruistic, and at other times the belief is shaded by a desire to win a person over to a particular denomination or administrative entity. Either way, the conventional religious wisdom is that we can—and should—“win people for Christ.”
However, this belief does not exist in a vacuum. A person's understanding of God's calling is linked with his belief in the different resurrections. It is crucial to the understanding of Pentecost and the Feast of Tabernacles because these festivals symbolize different physical and spiritual harvests—one early, smaller harvest and one later, much larger harvest. It shapes the understanding of the gospel of the Kingdom and tempers expectations on the effect when the world hears the gospel. If the scriptures about God's calling are broken, then many other core beliefs begin to break down as well.
