The book definition of unchangeable is not liable to variation or able to be altered: From a human perspective, you may claim to be stubborn and unchangeable, but the sinful condition will result in Peter like moments no matter how hard you try. Whether it’s “I’ll never do this” or “I’ll never say that,” there was a reason Solomon wrote, “pride comes before the fall,” Proverbs 16:18. Despite this fatal flaw, we do have a great high priest who is able to sympathize with our weaknesses, Hebrews 4:14-16.
This was so that, by two unchangeable things [His promise and His oath] in which it is impossible for God ever to prove false or deceive us, we who have fled [to Him] for refuge might have mighty indwelling strength and strong encouragement to grasp and hold fast the hope appointed for us and set before [us], Hebrews 6:18.
According to one New Testament author, there are two spiritual things that are unchangeable. God’s promise beginning in Genesis 3:15, brought up by Jesus in Luke 19:10 and fulfilled in Jesus’ resurrection, 1 Peter 1:3. The second is God’s oath sworn to Abraham in Genesis 12:1-3. While this promise seemed iffy as Sarah was unable to have children and became well beyond the age of a normal conception, but with God anything is possible. Abraham and Sarah learned this the hard way, despite doubting on numerous occasions.
[Now] we have this [hope] as a sure and steadfast anchor of the soul [it cannot slip and it cannot [c]break down under whoever steps out upon it—a hope] that reaches [d]farther and enters into [the very certainty of the Presence] within the veil, 20 Where Jesus has entered in for us [in advance], a Forerunner having become a High Priest forever after the order (with [e]the rank) of Melchizedek, Hebrews 6:19-20.
The passage above deals with the reality of doubt. When your faith starts to slip, God offers a sure and steadfast anchor. Symbolic of hope, the author is trying to remind flawed human beings of God’s power to endure and survive the storms of life. Although human beings will break their promises to one another, God’s promise and oath are guaranteed for life, 1 John 5:13-15. Therefore, don’t let anxiety, concerns and worry rock your faith. Rather, hold fast to the promises of the Bible, 2 Peter 1:3-4.
