We cannot truly live without hope. At the biological level, it is the teleological pull that is the driving force within every living creature, as well as the propelling mechanism for evolution. For humanity, it is realized as a conscious hope that gives us the will to persevere. It is the vision of future destiny communicated by the Spirit, driving humanity, and all life, and all creation, as a “final cause”.
The practical question is where to place or find our hope? Those who are thoughtful and honest about it will conclude there’s little if any hope to be found in this world (see e.g. Ecclesiastes). We must look instead to God, as for example in Psalm 39:7. The Christian faith and revelation places our hope more specifically in Christ (Col 1:27), validated by His resurrection. But there are further questions as to how this hope is to be understood, how it is to be established and made firm, and particularly how it applies to each individual. Three points to consider are: 1) the unchangeable faithfulness of God; 2) the power and wisdom of God, to accomplish His purpose; 3) personal application and assurance.
The first point, which is the least controversial, is that His steadfast love, “hessed”, endures forever. See especially Psalms 118 and 136. Classical orthodoxy, subject to NeoPlatonism, asserted that God is also unchangeable in all other respects, including impassivity. But I hold that to be contrary to scripture, and unnecessary for establishing our hope. What is needed, and what is affirmed in scripture, is that He keeps His promises, and nothing can separate us from His love. But He can nevertheless alter plans in response to His peoples’ prayers and their obedience or disobedience. His specific actions are contingent upon and responsive to the freely chosen behavior of the people He interacts with. Also, when Jesus wept, He faithfully revealed the compassion and griefs of the Godhead. But the unchangeable constant is His steadfast love.
Regarding the power and wisdom of God, scriptures clearly teach that it is unchallengeable. We see this especially in Genesis 1, Job 38-41, and Psalm 104. But that does not mean that He exercises it in a totally controlling and despotic manner, predetermining all human decisions and behavior. I believe such views partly derive from underestimating His love and His wisdom: a love that pays the cost of granting freedom to his loved ones, and a wisdom that can accomplish His purpose “light-handedly”. The position I describe (a form of open theism) does not entail any risks in regard to fulfilling His promises (as is the case for process theology), but it does entail a costly love – the love of kenosis – for the sake of respecting and preserving the integrity of humanity. He willingly and wisely restrains His exercise of power, treating us with gentleness and respect.
The reason why this should not weaken our hope, is that the scriptures also reveal His amazing wisdom and providence. Consider, for example, the story of Esther. The principal characters are all making free decisions, based on a wide range of motives: the evil intentions of Haman, the foolishness of the king, and the less than perfect motives of Esther and Mordecai. But God manages to make everything work together for His purpose. The key turning point in this drama was that the king suffered insomnia after a banquet (perhaps indigestion?). God’s “interventions” were natural, chance events, by which He changed the course of history, but never violating anyone’s free integrity. A God who can do this, is One in whom we can place our hope.
So the faithful love and the wisdom of God assures us of the hope for all who are in Christ. The remaining question for each individual is: “how do I know that I am in Christ; how can I be assured that I am among the saved?” I’ll suggest two key scriptures for answering this. Firstly, Rom 8:14-17 — “All who are being led by the Spirit of God, these are sons of God…. The Spirit himself testifies with our spirit that we are children of God…”. The indwelling presence of the Spirit shows us that we belong to Him. He is a pledge of our inheritance (Ephesians 1:14). And the definitive evidence of His indwelling is not particular gifts or signs, nor particular feelings, but rather the fruit (Galatians 5:22-23), which is produced by all who are “being led by the Spirit”. And the principal fruit is love, which is the subject of the second passage I would cite – 1 John 3:18-19 — “let us love … in deed and truth. We will know by this that we are of the truth, and will assure our heart before Him”. The practice of love gives assurance of His presence, not just because His presence assuredly yields the fruit of love, but more significantly, His presence is necessary for this kind of love. To love others the way Jesus loves us is possible only when Christ is in us. Therein is the assurance.
However, one might also be unsure about whether we really exhibit such love. So much of what we do is corrupted by mixed motives. How can we examine ourselves against the standard of the love of Christ? In Hebrews 6:9-12, we are exhorted to be diligent in continuing to love, in order to “realize the full assurance of hope”. We can follow this up with another key passage on hope: Rom 5:3-4 — “tribulation brings about perseverance; and perseverance, proven character; and proven character, hope…”. We can see here the value of being put to the test. If life is too easy, if we are never asked to pay a high price, it will be hard to know if the love of Christ is really in us. Consider the accusation against Job, which led to him being tested (Job 1:9-11). But when we pass through tribulation, and our character is thereby tested and proven, then we can know that we are loving the way Christ loves. We can know then that He is in us, and that the Spirit dwells in us, and that we are therefore his children, heirs to the promise.
