...But we're here on the earth now. So are you saying we should forget about this world altogether, and focus solely on God's Kingdom?
Because in Jesus' time, there was no voting. You had rulers and regular people... So how could he have promoted politics when not everyone could be a politician? ...You see what I'm saying? things have changed.
Yes, things have changed ( the scene of the world changes - 1 Corinthians 7:31 B)
Please notice John 6:15 because it mentions 'the people' wanted to make Jesus as their king/ ruler. Jesus declined.
In other words, Jesus could have been their king but it was Not the time for Jesus to begin ruling or governing over Earth.
Even some rulers were putting faith in Jesus, but because of the Pharisees (religious leaders) they would Not - see John 12:42
To me, how much better it would be for those ruling or governing to Not put so much importance on what others think.
Rather, think about what Jesus taught. Receiving or accepting honor from one another, and Not the glory that is from God,- John 5:44
Yes, we are here on Earth now, and according to Scripture 'Earth abides forever' and humble meek people will inherit the Earth.
So, No we are Not to forget about this world altogether, but that God's kingdom (Daniel 2:44) is the government to follow as Jesus did.
I suppose one could say by following or being committed to Jesus is already voting for Jesus.
If everyone on Earth followed Jesus they'd already be living by the Golden Rule and Jesus' New commandment of John 13:34-35.
Yes, thing have changed, changed to the point that we are in these last days of badness on Earth and see a selfish distorted from of love as described at 2 Timothy 3:1-5,13 which is in sharp contrast with the Christ-like love defined at 1 Corinthians 13:4-6.
Jesus taught to focus on God's kingdom (Matthew 24:14; Acts 1:8) as he focused on God's kingdom - Luke 4:43
Without kingdom focus people would Not know about the good times coming here on Earth - Isaiah 35th chapter; Revelation 22:2.
