Why has God hidden himself, and why can't God show me physical signs that he really exists? Since the creation of mankind, God has been saddened by our sins, because sins lead us to eternal death. He loves us so much and never gives up on us. Before the birth of Jesus, God kept showing his presence to mankind, and he even punished and destroyed the wicked ones to make humans feared him. He repeatedly called on mankind to repent by showing great miracles and signs, making them trembled before him. Even then, many still turned away from him, their hearts are so wicked, and they did all the sinful and evil things before God. He learned that by showing his presence to his beloved mankind could not save them. Because of God's love for us, he wants to save us, and he wants us to have eternal life. As such, God carried out his greatest plan for mankind, he sent his son Jesus to be crucified for our sins. In order to receive the salvation, there is only one condition; we must believe in Jesus by our own free will. By our own free will simply means we believe without seeing the presence of God. There is no evidence of God. No one can find him or prove his presence by reason and logic. You must believe in him, only because your heart chooses to do so by faith alone. This is the only condition to receive the salvation, made possible by the crucifixion of our Lord Jesus. To my understanding, because of this condition, God 'disappears' and 'hides' himself from the world. He does that to the extent of allowing Satan to cause sufferings and deaths to mankind, both Christians and non-Christians alike. God 'does not' reveal himself so that his great plan of Christianity and the crucifixion of Jesus (or God himself) are not made to vain. Obviously, to him, our salvation is much more important than showing his glory. Out of his love, God secretly shares with us our sufferings. In the twentieth century alone, the world population increased from one billion to six billions. God is working very hard to save as many souls as he can. While he is 'hidden' from the world physically, but spiritually, he is actively working in the hearts of many Christians to spread the Good News to the remaining four billions non-Christians worldwide. Interesting to note that God improves our communication technologies as the global population increases, so that his Good News can be easily reached out to the world, coincidence? end...
