Man is made in God’s image, i.e. capable of love and capable of thought.
But humans aren’t called to a life of ease, with God as a convenient “EASY Button,” or an ATM. Rather, humans are called to work, and as necessary to suffer. God made us to be born helpless, and gradually grow bigger, stronger, and more capable – then in old age the process kinda reverses.
Paul’s letter to the Ephesians spells part of it out for us – look at chapter 2, verses 8, 9 and 10. In particular, verse 10 makes it clear that God has designed us for work, AND has prepared a daily “opportunity list” for each of us – look at verse 10 and see if that isn’t clear.
We are also, because we are imperfect and incapable of avoiding sin, required to confess. It takes “a broken and contrite heart,” and that is what washes us free of our sins. Paul himself said that the good he wanted to do, didn’t get done, and the evil he wanted to avoid, happened anyway. His “most righteous acts” were, compared to the perfection of Jesus, tawdry and disgusting.
Martin Luther picked up on this, and in despair of his own said, “sin bravely” i.e. if our level best is flawed, just go ahead and DO SOMETHING.
As to why we have problems, that’s a long answer for another forum. Everyone has problems – so having difficulties makes us very ordinary, not at all unique. And god loves the ordinary person. He saved us from our sins – after a time on earth that is “smoke and mirrors” compared to what awaits us in the afterlife, the Charlie Wonka Gold Ticket is ours by living with God on our minds, patient hearts, and enduring praise for God at all times and in all places.
Just to be clear, we don’t say “Thanks for the broken arm!” – when we have a broken arm we say “Thanks for Forgiveness, Grace, and the sure expectation of Heaven.”
