Thus, we are not told that it is impossible to voluntarily leave God's protection. Rather, we are assured that no one can take us by force from God's hand as we sit helplessly. Furthermore, after examining more closely the unconditional security proof texts, I began to consider the many passages showing the conditional nature of righteousness. It is a theme that begins in the opening chapters of Genesis and continues through all of scripture. Each of the Old Testament covenants were clearly conditional, but false prophets tried to convince the Israelites that the conditions established by God were unfair, and that their security as believers was actually unconditional.
Scripture provides the correction.
But it is their way that is not just. If a righteous man turns from his righteousness and does evil, he will die for it. And if a wicked man turns away from his wickedness and does what is just and right, he will live by doing so. Other passages also confirm that it is possible for a righteous person to die. However, that the covenants were conditional does not mean that righteousness is the deserved product of any human work, nor does it mean that any power and glory belongs to believers.
