Trusting God for this task should be easy. Did he not do a perfect job in Jesus? Were his early disciples any harder than we are to convert? Whatever ground we offer to the Lord he will occupy fully. There are no half measures with him. Sometimes we may feel that way when we cannot summon any awareness of his presence. Jesus too went through such a time: “My God, my God. Why have you forsaken me?” (Mark 15:34) were the coldest words spoken at his crucifixion. And yet he, of all people, knew that God was anywhere but absent.
We need only to appear at his gates, so to speak, in order to enter his fortress and refuge (above). There are no other requirements. Who of us would turn a child away from our safekeeping because of bad behaviour, for instance? The story of the prodigal son (Luke 15) features the Lord rushing to meet his wayward son. No hint of retribution for the squandering of the inheritance. “Was lost.” “Now found”. End of story.
So it is with us. We can enter his fortress at any time. There is no chance that the drawbridge won’t be down waiting.
