Many of us have at one time or another come in contact with those who could care less about serving God. Some may ask why does God allow wickedness in the earth, while others may wonder how long will it continue and does God really notice? Such questions were also asked by David the psalmist where we find nothing goes unnoticed by God! Even though the wicked press on in their evil ways God gives rest unto His people through their adversity while the pit is being dug for the wicked (Psalm 94:1-13) O Lord God, to whom vengeance belongeth; O God, to whom vengeance belongeth, shew thyself. Lift up thyself, thou judge of the earth: render a reward to the proud. Lord, how long shall the wicked, how long shall the wicked triumph? How long shall they utter and speak hard things? and all the workers of iniquity boast themselves? They break in pieces thy people, O Lord, and afflict thine heritage. They slay the widow and the stranger, and murder the fatherless. Yet they say, The Lord shall not see, neither shall the God of Jacob regard it. Understand, ye brutish among the people: and ye fools, when will ye be wise? He that planted the ear, shall he not hear? he that formed the eye, shall he not see? He that chastiseth the heathen, shall not he correct? he that teacheth man knowledge, shall not he know? The Lord knoweth the thoughts of man, that they are vanity. Blessed is the man whom thou chastenest, O Lord, and teachest him out of thy law; That thou mayest give him rest from the days of adversity, until the pit be digged for the wicked.

God knows and sees the people who choose to trouble us and He alone will repay tribulation to them (2 Thessalonians 1:4-10) So that we ourselves glory in you in the churches of God for your patience and faith in all your persecutions and tribulations that ye endure: Which is a manifest token of the righteous judgment of God, that ye may be counted worthy of the kingdom of God, for which ye also suffer: Seeing it is a righteous thing with God to recompense tribulation to them that trouble you; And to you who are troubled rest with us, when the Lord Jesus shall be revealed from heaven with his mighty angels, In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ: Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power; When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed) in that day. 

When we see those before us who clearly do not bat an eye as they do their evildeeds, may we always keep in mind God will repay them to their face as it is clear they do not love God and His righteous ways! (Deuteronomy 7:9,10) Know therefore that the LORD thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations;  And repayeth them that hate him to their face, to destroy them: he will not be slack to him that hateth him, he will repay him to his face. 

God knows those who are His (2 Timothy 2:19)

Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord. Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire in his head. Be not overcome of evil, but overcome evil with good. (Romans 12:19-21).
