1 Thessalonians 5:23-24
Ever since the heavenly Father created time, everything has been in flux—everything, that is, except God Himself. The environment changes with the seasons, and in a similar way, our life also goes through seasons. Some are filled with joy, while others are characterized by difficulty. But the Lord is faithful, and we can always take comfort in knowing this.
Faithfulness is one of God’s unchanging attributes. It means that He always does exactly what He says He will do and acts in accordance with His nature. He can never deny Himself, so when He promises to “sanctify you entirely” (1 Thess. 5:23), you can count on Him to make you more like Christ—even using the painful seasons of life to do so.
God’s unchanging nature and faithfulness are the foundation of our hope. Because He won’t change His mind about our salvation, we have the assurance of eternal security. Since He is the sovereign Ruler of the universe, we never have to fear that our world is out of His control. His plans were formed long ago with perfect faithfulness (Isa. 25:1), and no one can frustrate them or turn back His hand (Isa. 14:27).
Because God is faithful, we can have peace of mind in any circumstance—even in the face of death. Although we will change with time and the seasons of life will come and go, our faithful God is always the same. Since we belong to Him through Christ, He will never forget, neglect, or abandon us. He has promised to preserve us “complete, without blame at the coming of our Lord Jesus Christ” (1 Thess. 5:23), and He will do it.
