Let's say you're trying to convince a sinner who has somehow gotten the wrong impression. Maybe he's afraid God hates him, or is out to get him.
How do you make your case and convince him otherwise?
Thats why God
came in the flesh, to demonstrate and prove that He’s not some angry, distant being, aloof in His superiority, but a God who’s not opposed to getting His hands dirty, coming down and mixing it up with His own creation while showing that He’s always been on man’s side, always loved and wanted the very best for us. Enmity and jealousy and distance came from man, not Him.
He healed the sick, taught and showed that humility, gentleness, mercy and love were superior human traits, truly attainable as we enter fellowship with Him, and suffered an excruciatingly humiliating and painful passion and death in human flesh to demonstrate the extent He’d go in order to prove a love so vast and wide and deep that we can just barely begin to understand, and be moved by it. And to cap it He overcame death-and so our fear of it- by His resurrection, revealing that we were created to live eternally as well. He revealed what we need to know. We need
Him in order to know anything truly worth knowing, we need Him in order to have eternal life. We need Him just in order for goodness to fully reign in the human heart. “Apart from Me you can do nothing”. John 15:5
Aside from that we see His handiwork. Alongside of various evils that we will experience in this world is the undeniable good inherent in creation: the beauty of nature, friendship, love, joy, laughter, gaining and growing in knowledge and understanding, pleasure, etc.
