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.

O MY SAVIOUR,
Help me.
I am so slow to learn,
so prone to forget,
so weak to climb;
I am in the foothills when I should be
on the heights;
I am pained by my graceless heart,
my prayerless days,
my poverty of love,
my sloth in the heavenly race,
my sullied conscience,
my wasted hours,
my unspent opportunities.
I am blind while light shines around me:
take the scales from my eyes,
grind to dust the evil heart of unbelief.
Make it my chiefest joy to study thee,
meditate on thee,
gaze on thee,
sit like Mary at thy feet,
lean like John on thy breast,
appeal like Peter to thy love,
count like Paul all things dung.
Give me increase and progress in grace
so that there may be
more decision in my character,
more vigour in my purposes,
more elevation in my life,
more fervour in my devotion,
more constancy in my zeal.
As I have a position in the world,
keep me from making the world my position;
May I never seek in the creature
what can be found only in the Creator;
Let not faith cease from seeking thee
until it vanishes into sight.
Ride forth in me, thou King of kings
and Lord of lords,
that I may live victoriously,
and in victory attain my end.
Valley of Vision

Stephen Charnock reminds us that no matter how great our thoughts of God, he is greater still!
Whatsoever God is, he is infinitely so: he is infinite Wisdom, infinite Goodness, infinite Knowledge, infinite Power, infinite Spirit; infinitely distant from the weakness of creatures, infinitely mounted above the excellencies of creatures: as easy to be known that he is, as impossible to be comprehended what he is. Conceive of him as excellent, without any imperfection; a Spirit without parts; great without quantity; perfect without quality; everywhere without place; powerful without members; understanding without ignorance; wise without reasoning; light without darkness; infinitely more excelling the beauty of all creatures, than the light in the sun, pure and unviolated, exceeds the splendor of the sun dispersed and divided through a cloudy and misty air: and when you have risen to the highest, conceive him yet infinitely above all you can conceive of spirit, and acknowledge the infirmity of your own minds. And whatsoever conception comes into your minds, say, This is not God; God is more than this: if I could conceive him, he were not God; for God is incomprehensibly above whatsoever I can say, whatsoever I can think and conceive of him.
