In the eyes of the nonbeliever, God is never fair in what He does. When men suffer the consequences of flaunting God's grace or breaking His commandments, they blame God and call Him unjust. The fact is that God is completely just. He is faithful and true. Writing about Jesus, the apostle John said, "Now I saw Heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness He judges and makes war." (Revelation 19:11).
In contrast to this, the devil is unfaithful and a liar. Jesus described him as "a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it" (John 8:44).
One thing we learn about the Lord after we have walked with Him for a while is that He keeps His promises—all of His promises. For instance, He has promised to never leave us nor forsake us (see Hebrews 13:5). He has promised to bring His peace into our lives (see John 14:27). He has promised to come again: "And if I go and prepare a place for you, I will come again and receive you to Myself; that where I am, there you may be also" (John 14:3).
In fulfillment of His promise, Jesus will come back and will judge the earth. And it will be fully deserved. There is nothing arbitrary or unjust about His judgment. Some might ask how a God of love could bring judgment. But how could a God of love not
bring judgment? God has said there are penalties for sin. Yet He offers so many opportunities for us to believe.
