The God who reveals himself to us in the Bible is a covenant keeping God. He is always faithful to his word, he always keeps his promises and imparts grace to his children. sometimes as we look at the picture of God that is presented to us in the Bible we get perplexed with concepts such as our God does not change. Sometimes this is communicated in such away that we get the impression of an immobile God but we know that cannot be correct. The Bible clearly portrays a God who reacts with us, so he can’t be unchangeable in this way of thinking.
When we think of people not changing we think of obstinate people who resist every change but the bible portrays a God who brings radical change to human beings, the new birth being the primary example. so how do we bring these two things together a God who does not change and yet delights in seeing humans change. Firstly it should be made clear that we need to define our terms the changeableness of God means that he does not change in his character or attributes. God is always a God of grace seeking to change people more and more into the image of His Son. He is the God of holy love, who has always been full of compassion for fallen human beings. He is in his character always totally pure and holy. ( see Lamentations 3 and Malachi 3)
What is more his power to express his love and grace is never diminished, when we serve others we know that we lose strength but our God does not his strength is always the same. The knowledge that this God is the Sovereign who can do whatever he wants has always been an encouragement to believers {Look at the believers prayer in Acts 4 and the prayers in Ephesian 1 and 3).
His love can never be exhausted, nor can he be emotionally drained, he is always the same in love, compassion and power. Obviously we are standing in an ocean of god’s truth that is hard to express but try we must to lisp something of his wonderful Character.
We look at the word of God and we see revealed there the perfectly righteous and Holy God before whom we stand in awe and wonder. The knowledge that our God is so great calls us to worship and serve him.
We must realise that he also is the God who keep all of his covenant promises, He is the only person who can truly claim to have kept all of his promises. When God gives a promise in his Word we know that he will not fail to keep it. When we were born again we became part of a family that is bound by the strongest of ties to the heart of our father God, by this bond of love we can be assured that the eternal love and power of God is for us and no one can defeat him. It is because he is unchangeable in his character that we can have confidence in him and his purposes for our lives.
