God does not change in his being, attributes, purposes, or understandings. This does not mean he is rigid and unemotional, for a quick read through the stories of the Old Testament shows that God is responsive and moved by emotion. So, what does this mean?
While God sometimes changes his short term acts (Exodus 32:11-14; Jonah 3:10), he always keeps his promises (Numbers 23:19) and his intentions stand forever (Psalm 33:11). Though creation changes and decays, God does not change; he remains forever (Psalm 102:26-27). Because God keeps his promise to bless and keep his people, they are not cast aside when they sin (Malachi 3:6). He reassures his people by basing his unchangeable promises on his unchangeable self (Hebrews 6:13-18). God's unchangeable goodness is the source of all goodness (James 1:17).
Those who have trusted Christ can be assured of God's unchanging, steadfast love. Unfortunately, the reverse is also true: those who have not trusted, have no assurance and no hope apart from Christ. In this, God is also unchangeable (John 14:6).
Who are you trusting?
