Because the word translated as "come" here is not in the Greek future tense, but in the "second aorist" tense, many modern Bible translations correctly render this as "Let your kingdom come" or "May your Kingdom come," giving the solid idea of a future certainty. God's Kingdom will come. Jesus knew that it would come, but He wants His brothers and sisters to pray relentlessly for its coming, that it will come as soon as possible!
Thy Kingdom Come! (Part Two)
It is interesting to note in this model prayer that sin is expressed through the image of debt, a true metaphor. Duty neglected, a debt to God, must be discharged by a penalty. All have sinned and the wages or penalty is death (Romans 3:23; 6:23). We are all under a peculiar form of indebtedness which we cannot pay and still have hope!
