Jesus and the Already/Not Yet Kingdom

Jesus' opening proclamation — 'The time has come. The kingdom of God has come near. Repent and believe the good news!' (Mark 1:15) — is the most important eschatological statement in the New Testament. 'The time has come' (kairos) means the decisive moment of God's action has arrived. 'The kingdom of God has come near' means God's reign — his sovereign, saving, restoring rule — is breaking into the present. This is not merely a future hope; it is a present reality. When Jesus heals the sick, the kingdom is present. When he casts out demons, the kingdom is advancing. When he forgives sins, the kingdom is operative. When he raises the dead, the kingdom is triumphing over death itself. 'If I drive out demons by the finger of God, then the kingdom of God has come upon you' (Luke 11:20). This is the 'already' dimension. The kingdom is here — in Jesus, in the Spirit, in the community of believers. But it is not yet fully here. Sickness continues. Sin persists. Death still reigns. Creation still groans. We live in the overlap of the ages — the old age of sin and death is passing away, and the new age of God's kingdom is breaking in, but the transition is not yet complete.

Jesus' parables reveal the kingdom's surprising nature. The mustard seed (Mark 4:30-32): the kingdom starts absurdly small but grows beyond all expectation. The yeast (Matthew 13:33): the kingdom works invisibly, permeating everything it touches. The treasure and the pearl (Matthew 13:44-46): the kingdom is worth everything — total, joyful, all-in commitment. The wheat and weeds (Matthew 13:24-30): the kingdom grows alongside evil, and God will sort it out — not human vigilantes. The great banquet (Luke 14:15-24): the kingdom's invitation goes to the unexpected — the poor, the disabled, the outsiders — when the 'respectable' refuse to come. These parables challenge every expectation. The kingdom does not come with fanfare but with patience. It does not begin with the powerful but with the marginalised. It does not operate by force but by transformation from within. For churches in Botswana: do not measure kingdom success by size, wealth, or public influence. Measure it by transformation — lives changed, relationships healed, justice pursued, love embodied. The mustard seed church in a rural village may be more 'successful' in kingdom terms than the mega-church in the city.

In Matthew 24-25 (parallels in Mark 13, Luke 21), Jesus delivers his most extended eschatological teaching. His disciples ask: 'When will this happen, and what will be the sign of your coming and of the end of the age?' Jesus' response is complex, weaving together: (1) The destruction of the Jerusalem Temple (fulfilled in 70 AD); (2) The tribulations that will characterise the entire period between his first and second coming — wars, famines, earthquakes, persecution, false prophets; (3) His future return in glory. The critical warning: 'About that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father' (Matthew 24:36). This verse should settle all date-setting and prediction-making. Jesus explicitly says we cannot know when he returns. The appropriate response is not speculation but readiness — the parable of the wise and foolish virgins (Matthew 25:1-13), the parable of the talents (Matthew 25:14-30), and the sheep and goats (Matthew 25:31-46). The sheep and goats is especially important: the criterion of judgment is not doctrinal precision or religious performance but concrete love for 'the least of these' — the hungry, the thirsty, the stranger, the naked, the sick, the imprisoned. Eschatology is not an excuse to disengage from the world; it is a call to radical engagement with the vulnerable.

The cross and resurrection of Jesus are not merely historical events — they are the eschatological turning point of cosmic history. On the cross, the powers of sin, death, and evil did their worst — and were defeated. 'Having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross' (Colossians 2:15). The resurrection is not just proof that Jesus was right; it is the first act of the new creation. When God raised Jesus from the dead, he inaugurated the future in the present. The resurrection body of Jesus is the first installment of the new heavens and new earth. Paul calls Jesus 'the firstfruits of those who have fallen asleep' (1 Corinthians 15:20) — the guarantee that the harvest is coming. This changes everything. Death is real, but it is not ultimate. Suffering is painful, but it is not permanent. Evil is powerful, but it is not sovereign. The resurrection is God's definitive 'Yes!' to life, to creation, to bodies, to the material world. Any theology that is embarrassed by bodies, by the earth, by material reality has not reckoned with the resurrection. The risen Jesus ate fish (Luke 24:42-43) — the new creation is not disembodied spiritual existence but renewed, healed, embodied life.

Pentecost is an eschatological event. When the Spirit was poured out on the church (Acts 2), Peter interpreted it through Joel's prophecy: 'In the last days, God says, I will pour out my Spirit on all people' (Acts 2:17). The Spirit is the 'deposit guaranteeing our inheritance' (Ephesians 1:14) — the down payment of the future, given now. Living in the Spirit is living in the overlap of the ages. The Spirit gives us foretastes of the coming kingdom: healing (not all healing, but some — the already/not yet), transformed relationships, supernatural love, prophetic insight, and power for witness. The Spirit also makes us groan — 'the Spirit himself intercedes for us through wordless groans' (Romans 8:26). This groaning is not a sign of failure but of eschatological tension. We experience enough of God's kingdom to know what we are waiting for, and enough of the present age to know that we are not yet there. This is the normal Christian life: joy and groaning, power and weakness, victory and struggle — all at the same time.

The 'already/not yet' framework has profound implications for daily Christian life. We worship with both celebration and longing. We pray 'Your kingdom come' because it has come and is still coming. We pursue justice knowing that full justice awaits Christ's return, but refusing to use that as an excuse for passivity. We grieve — honestly, deeply — while holding onto hope. We experience healing but do not pretend that all are healed. We experience victory over sin but do not pretend we are sinless. This framework protects us from the dangers of over-realised eschatology (the claim that the kingdom is fully here — which leads to triumphalism, prosperity gospel, and denial of suffering) and under-realised eschatology (the claim that the kingdom is only future — which leads to passivity, escapism, and indifference to injustice). The church is called to be a sign, foretaste, and instrument of the coming kingdom: a sign that God's future is real, a foretaste of what is to come, and an instrument through which God is already working to transform the world. In Botswana, this means we do not just preach about heaven — we work for justice, care for the sick, feed the hungry, and build communities of love. Because the kingdom has already begun.
