(The following is the October 30 devotional from my Next Step Devotions book. Before reading it, I suggest you read Hebrews 13 and pay close attention to verse 8.)

“Jesus Christ is the same yesterday, today, and forever” (v. 8). How wonderful is it that we serve an unchanging God? How comforting is it to know that the God revealed in Scripture thousands of years ago is still the same? Other passages affirm this truth:

• “God is not a man, that he might lie, or a son of man, that he might change his mind” (Num. 23:19).
• “I, the Lord, have not changed” (Mal. 3:6).
• “Every good and perfect gift is from above, coming down from the Father of lights, who does not change like shifting shadows” (James 1:17).

There is only one God, and he exists in three persons – Father, Son, and Holy Spirit. This Trinity has always existed and always will. No person of the Trinity has changed, nor will they. They are perfect and complete, so no change is necessary.

What are some implications of the fact that God is the same yesterday, today, and forever? There are at least three:

• The truth of his Word never changes. “There is no such thing as new and improved Christianity.” *
• We can recognize false teaching. Any teaching that conflicts with what our unchanging God has revealed in Scripture is untrue. We must reject it.
• God is trustworthy. “Our faith and hope and knowledge all ultimately depend on a person who is infinitely worthy of trust – because he is absolutely and eternally unchanging in his being, perfections, purposes, and promises.” **

Next Step:
Are you aware of churches or self-proclaimed Christians who teach contrary to what the Bible teaches and what historic Christianity has affirmed for many centuries? Study Bible passages related to those subjects and hold firm to what our unchanging God has revealed.
