I know God exists, I'm not stupid. - Ray Comfort

When we are first born into God’s kingdom we generally get our prayers answered immediately, but as we grow God teaches us patience by letting us wait.

In Christianity, God Himself provided a “parachute” for us, and His word says regarding the Savior, “Put on the Lord Jesus Christ.” Just as a parachute solved your dilemma with the law of gravity and its consequences, so the Savior perfectly solves your dilemma with the Law of God and its consequences! It is the missing puzzle-piece that you need. How did God solve our dilemma? He satisfied His wrath by becoming a human being and taking our punishment upon Himself. The Scriptures tell us that God was in Christ, reconciling the world to Himself. Christianity provides the only parachute to save us from the consequences of the Law we have transgressed.

On Judgement Day, those who think such talk is 'fear mongering' will find out that it's not. It is simply the truth, and they will wish to God (understatement) that they had obeyed the Gospel.
