"I am the Lord.  I change not." Malachi 3:6

"Jesus Christ the same yesterday, and today, and forever." Hebrews 13:8

God never changes who He is. He is always consistent.   He is not fickle.  He was not a different God in the Old Testament or to your grandparents. He is and always has been the same God.
     He is Holy (He keeps His promises).
     He is Righteous (He always does what’s right).
     He is Good (He loves us and is always working in us and for us)

These things never change!

"God Is Love, God is Light
God is faithful day and night
He is eternal, He never changes
Though the seas rise up to swallow mountain ranges"
