How can a God who is both all-powerful and all-good allow evil to continue without eradicating it? The problem with evil is presented as a problem with God and therefor, a problem with our faith as Christians. The voices of the atheist community are the main leaders in this demonic agenda against the essence of God’s character, his goodness. But the issue is not a complicated one at all. God made us free!
I am convinced that the same people complaining against the result of our freedom (evil) would be the same people complaining if God decides to make robots out of us. The Garden of Eden represents the perfect will of God for us. However, Adam and Eve introduced evil in this world by disobeying God. There is no other explanation! I am glad that in spite of Adam and Eve disobedience and, in spite of our current condition, God is not giving up on us.
God is not the problem, we are! In fact, God gave us the redemptive plan through Jesus Christ. In Christ God manifest his love and goodness towards us. This explanation, however, will never be sufficient to the lost; they need the miracle of salvation (Ephesians 2:8-9). To think that salvation will come through intellectual arguments is not biblical. Apologetics is not about professional debates; is about the simplicity of somebody asking us why we believe what we believe and us having enough understanding of our faith to give a solid, loving and humble answer. (First Peter 3:15)
But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, 16 keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander. First Peter 3:15-16 (NIV)
