Reading the poetic portions of the Old Testament in English, especially in the Prophets, can be challenging. But the fact is that the more familiar one becomes with the poetic sections of the Prophets, the more one sees that they are absolutely, vitally central to the NT. In the end, the way to make OT poetry interesting and understandable is not by retreating from it but by studying it even more intensely using all the imaginative and scholarly resources at your disposal.
God’s love for us is unreasonable – it is not based on reasons but merely on God’s sovereign decision. The resurrection of Jesus is also unreasonable in that it lies beyond the realm of reason either to prove or disprove. This is why it is the perfect demonstration of God’s unreasonable love. It is also why our unreasonable faith in the resurrection is the perfect human response to God’s unreasonable love.
