God is unchanging in His demand for holiness and integrity in our lives: " Consecrate yourselves and be holy, because I am holy"( Leviticus 11:44; 1 Peter 1:14-15)
God is unchanging in His judgment: He will judge all the earth, welcoming some into His eternal presence and sending others to eternal death( Matthew 7:22-23).
God is unchanging in His love: He sent His Son to die on the cross for us sinners.
" I the Lord do not change."- Malachi 3:6
