There can be deep sorrow and grieving alongside our hope in the Lord, and our faith that he will redeem all of this for our good. We can grieve over things we are missing, and be hopeful that God is doing big important things in his time; these two things can coincide. It is not either or, it is all of it, together.
We are sinners, we are condemned (without Jesus), but we were not put on this earth to condemn others. We were called to love. When Jesus was asked what was the greatest commandment his answer was to love God, and then love your neighbor. He did not say love God, and then point out to your neighbor all the things he is doing wrong. Or love God and make sure everyone follows all the rules that are in the bible. He said love them, just love them.
