It is a wonderful thing to know that our God never changes. Though we and the world around us may change, not one of his eternal plans nor a smidgen of his character has budged throughout all eternity. Not even a shadow of change exists in him (James 1:17). This includes the ways in which he deals with mankind.
Listen to the words of J.I. Packer:
Still he blesses those on whom he sets his love in a way that humbles them, so that all the glory may be his alone. Still he hates the sins of his people, and uses all kinds of inward and outward pains and griefs to wean their hearts from compromise and disobedience. Still he seeks the fellowship of his people, and sends them both sorrows and joys in order to detach their love from other things and attach it to himself. Still he teaches believers to value his promised gifts by making them wait for those gifts, and compelling them to pray persistently for them, before he bestows them. So we read of God dealing with his people in the Scripture record, and so he deals with them still. His aims and principles of action remain consistent; he does not at any time act out of character. Our ways, we know, are pathetically inconsistent — but not God’s.
