He has finished everything on the cross, once and for all. All the injustice, poverty, and troubles were paid for and suffered for by Jesus.
Those small things like computer glitches are means for our faith to grow so we can pray for the much larger problems which were previously listed. At the same time, it shows the personal nature of our relationship with Him!!! He cares for the very minute details and frustrations we have.
The question is about faith. We can burn with hate and anger that God hasn't done this or that, but in reality, He's waiting for us to rise up in prayer and to go forward into the world to make a change. But, it's about Him and not us! We can't change a thing in and of ourselves. By the power of the Holy Spirit, we can see the Kingdom of God --- healing, forgiveness, peace, true joy, true love, relationship with our Dad in heaven --- come on earth.
