If we read the Book of Psalm 10:1-18, we will see clearly how it appears that the wicked in this world always succeed. They become extremely arrogant and they gloat over their desires, while boasting of abusing God. They make foolish jokes about "Where is this God that you are always talking about?" They say to their friends, "Let us go and eat, and drink and be merry because tomorrow we die." They have no respect for God and of course they do not believe in eternal life.
We need to pray for these people very sincerely, because The Bible tells us that every knee will bow, and every tongue will confess that Jesus Christ is Lord. (Romans 14:11). The righteous and unrighteous will be judged accordingly. Psalm 10 goes on to say that the wicked man's mouth is filled with curses, deceit and with cunning plans. His thoughts are harm and evil. He is continually working out how he's going to take advantage of the innocent, the poor, the widow and the orphan. He literally prowls around like a lion, waiting to take advantage of the poor. He catches the needy and pulls the net tight.
How often do we see this happening today and many people say, "Lord, where is Your justice?" Never forget that every single one of us, will be judged accordingly on the day of judgement. I don't know how many agnostics and those who have turned their backs on God come and say to me, "This God of yours, you say is a ‘God of justice.' How can people like (and they use the names of the tyrants) of this world go free and just do what they please?" Well the answer to that question is, they will not go free and ultimately, they will not do as they please, because the day of judgement is coming for them. So, if anything, we need to really pray for those who oppress us because their judgement will be extremely severe.
My excuse before I gave my heart to Jesus Christ was that if so-and-so is a Christian, then I will go to heaven before Him, because he does not even feed his family, he does not honour his wife, and he does not pay his staff a decent days pay for a decent days work, but it was only after I gave my life to the Lord, that I realised that on the day of judgement, the man that I thought was a Christian because he said so, was not even to be found in Heaven, because the Lord does not know him. We need to be more concerned about our own salvation, our lifestyle and the way in which we manage our own lives, rather than to be concerned about the evil whom the Lord will judge accordingly. He has promised us that very clearly in Psalm 10. Jesus says in Matthew 7:5 (NKJV), "Hypocrite! First remove the plank from your own eye, and then you will see clearly to remove the speck from your brother's eye."
We need to understand that no one on this earth will get away scott free for actions of greed, hatred, violence, or selfishness. Every single man will have to give an account for his life on earth.
So, may God bless you, as you take into consideration your own life before you are concerned about the supposed success of the evildoer. He will be judged by a very just and gracious God.
