If God is not ultimately in control over even the times of suffering & great tragedy in this life, then He is no real god at all.
We have a tendency, I think, to see God in the “good” outcomes, and yet, we fail to see Him ever-present even in the midst of trials because that is somehow easier for our finite minds to comprehend (at least at a basic level). However, if we think deeply about this, we will see that if God is not ultimately in control of ALL things, then how can we possibly trust Him to be able to save us or to keep the promises that He has made in His Word?
And if we do trust in His promises, then we have hope that one day all the evil of this present world will be gone. One day the world will be made new. One day we will have no sorrow, no suffering, no pain, & no questions of “Why?” Jesus has secured this hope through his death & resurrection, & the Holy Spirit has sealed that hope in us for those who believe. There is no true hope apart from Christ Jesus; there is only wishful thinking. And wishful thinking is no hope at all.
Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. Through him we have also obtained access by faith into this grace in which we stand, and we rejoice in hope of the glory of God. Not only that, but we rejoice in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope, and hope does not put us to shame, because God’s love has been poured into our hearts through the Holy Spirit who has been given to us.
For while we were still weak, at the right time Christ died for the ungodly. For one will scarcely die for a righteous person—though perhaps for a good person one would dare even to die—but God shows his love for us in that while we were still sinners, Christ died for us. Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God. For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life. More than that, we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation. (Romans 5:1-11 ESV)
For I consider that the sufferings of this present time are not worth comparing with the glory that is to be revealed to us. For the creation waits with eager longing for the revealing of the sons of God. For the creation was subjected to futility, not willingly, but because of him who subjected it, in hope that the creation itself will be set free from its bondage to corruption and obtain the freedom of the glory of the children of God. For we know that the whole creation has been groaning together in the pains of childbirth until now. And not only the creation, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for adoption as sons, the redemption of our bodies. For in this hope we were saved. Now hope that is seen is not hope. For who hopes for what he sees? But if we hope for what we do not see, we wait for it with patience.(Romans 8:18-25 ESV)
In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory. (Ephesians 1:13-14 ESV)
Now faith is the assurance of things hoped for, the conviction of things not seen.(Hebrews 11:1 ESV)
