Mark 1:12-15--four verses in which a LOT happens. Read them here and notice that in this passage, we get Jesus' first words in this Gospel:
‘The time is fulfilled, and the kingdom of God has come near; repent, and believe in the good news.’
But what IS the kingdom of God? Here is some of what Jesus says about it elsewhere in Mark:
'The kingdom of God is as if someone would scatter seed on the ground, and would sleep and rise night and day, and the seed would sprout and grow, he does not know how.'
‘With what can we compare the kingdom of God, or what parable will we use for it? It is like a mustard seed, which, when sown upon the ground, is the smallest of all the seeds on earth; yet when it is sown it grows up and becomes the greatest of all shrubs, and puts forth large branches, so that the birds of the air can make nests in its shade.’
‘Let the little children come to me; do not stop them; for it is to such as these that the kingdom of God belongs.Truly I tell you, whoever does not receive the kingdom of God as a little child will never enter it.’
‘How hard it will be for those who have wealth to enter the kingdom of God!...It is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God.’
Then the scribe said to him, ‘You are right, Teacher; you have truly said that “he is one, and besides him there is no other”; and “to love him with all the heart, and with all the understanding, and with all the strength”, and “to love one’s neighbor as oneself”,—this is much more important than all whole burnt-offerings and sacrifices.’ When Jesus saw that he answered wisely, he said to him, ‘You are not far from the kingdom of God.’
“If we only had eyes to see and ears to hear and wits to understand, we would know that the Kingdom of God in the sense of holiness, goodness, beauty is as close as breathing and is crying out to born both within ourselves and within the world; we would know that the Kingdom of God is what we all of us hunger for above all other things even when we don’t know its name or realize that it’s what we’re starving to death for. The Kingdom of God is where our best dreams come from and our truest prayers. We glimpse it at those moments when we find ourselves being better than we are and wiser than we know. We catch sight of it when at some moment of crisis a strength seems to come to us that is greater than our own strength. The Kingdom of God is where we belong. It is home, and whether we realize it or not, I think we are all of us homesick for it.”
― Frederick Buechner
"What you do in the present—by painting, preaching, singing, sewing, praying, teaching, building hospitals, digging wells, campaigning for justice, writing poems, caring for the needy, loving your neighbor as yourself—will last into God’s future. These activities are not simply ways of making the present life a little less beastly, a little more bearable, until the day when we leave it behind altogether. They are part of what we may call building for God’s kingdom.”
― N.T. Wright
“I'm fairly convinced that the Kingdom of God is for the broken-hearted. You write of 'powerlessness.' Join the club, we are not in control. God is.”
― Fred Rogers (Mr. Rogers, to you!)
"When we see social relationships controlled everywhere by the principles which Jesus illustrated in life -- trust, love, mercy, and altruism -- then we shall know that the kingdom of God is here."
-Martin Luther King, Jr.
