What are the benefits of obeying the Gospel of the Kingdom of God?

"And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel." (Mark 1:15 KJV)  "And as they heard these things, he added and spake a parable, because he was nigh to Jerusalem, and because they thought that the kingdom of God should immediately appear." (Luke 19:11 KJV)  "When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?   And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power. (Acts 1:6-7 KJV) "And it shall come to pass in the last days, that the mountain of the LORD'S house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it. And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem.  And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more." (Isaiah 2:2-4 KJV) "For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this." (Isaiah 9:6-7)  Deuteronomy 28:1-14
