3. God Makes the Rainbow as a Symbol of His Covenant With Man
says, "Even though God made a covenant with mankind using the rainbow, He never told anyone why He did this, why He established this covenant, meaning He never told anybody His real thoughts. This is because there is no one who can comprehend the depth of the love God has for the mankind He created with His own hands, and there is also no one who can appreciate just how much pain His heart suffered when He destroyed humanity. Therefore, even if He tells people how He feels, they cannot undertake this trust. Despite being in pain, He still goes on with the next step of His work. God always gives His best side and the best things to mankind while quietly bearing all the suffering Himself. God never openly discloses these sufferings. Instead, He endures them and waits in silence. God’s endurance is not cold, numb, or helpless, nor is it a sign of weakness. It is that God’s love and essence has always been selfless. This is a natural revelation of His essence and disposition, and a genuine embodiment of God’s identity as the true Creator."
