So much suffering, wreckage on earth: if God exists, why does He not care?

Acts 2:19-21 EMTV

(19)  And I will give wonders in the heaven above, and signs on the earth below, blood and fire and vapor of smoke.

(20)  The sun shall be changed into darkness, and the moon into blood, before the coming of the great and awesome Day of the Lord.

(21)  And it shall be that everyone who calls on the name of the Lord shall be saved."
