That’s a question that’s wrestled with in Midrash Tehillim, a collection of rabbinic interpretations on the Book of Psalms. Our passage today comes from Midrash Tehillim 65, and it opens with the powerful phrase, "Nora'ot b'tzedek ta'anenu Elohei yeshu'otenu" – "Awesome things with righteousness You answer us, O God of our salvation."

The text then recounts a conversation between Rabbi Chanina bar Papa and Rabbi Shmuel bar Nachmani. Rabbi Chanina asks a rather cryptic question: "What does it mean, 'Her Sukkah is in a cloud for us?'" Now, a sukkah is a temporary dwelling, a booth constructed for the festival of Sukkot, and it's meant to be open to the elements, somewhat fragile. So what does it mean to say it's in a cloud?

Rabbi Shmuel answers with a profound insight: "The gates of prayer are sometimes open and sometimes closed, but the gates of repentance are never closed." He illustrates this with a beautiful analogy, drawing from the verse "The hope of all the ends of the earth and of the distant seas." Just as the sea is always open to anyone who wishes to bathe in it, so too, the gates of teshuvah, of repentance, are always open to anyone who wishes to return to God. And, crucially, the Lord accepts him. Prayer, on the other hand, has its specific times, its appointed moments.

Rabbi Yosei bar Chalafta echoes this sentiment, quoting Psalm 69:14: "And as for me, let my prayer come to You, Lord, at a favorable time. In the abundance of Your mercy, answer me with the truth of Your salvation." There are, indeed, times for prayer.

But then, the discussion takes an interesting turn. Rabbi Berekiah, Rabbi Chilbo, and Rav Anan bar Yosef, citing Rav Idi, offer a different perspective: even the gates of prayer are never closed. A bold claim!

This leads to a disagreement between Ben Azzai and Rabbi Akiva, two towering figures of Jewish thought. One of them argues that whoever practices kindness can be confident that their prayer is heard, referencing Hosea 10:12: "Sow righteousness for yourselves, reap the fruits of mercy." The verse continues, "Break up your fallow ground, for it is time to seek the Lord." The implication is clear: prayer follows righteous action.

The other, either Ben Azzai or Rabbi Akiva, adds another layer, saying, "I do not reject the words of Rabbi, but I add to them." They quote Psalm 5:8: "But as for me, through the abundance of Your steadfast love, I will enter Your house; I will bow down toward Your holy temple in awe of You." The verse concludes with a plea: "Answer me, God, in Your faithfulness, in Your salvation that never fails."

So, what are we to make of all this? Do the gates of prayer open and close? Or are they perpetually accessible? Perhaps the answer lies in the tension between these different perspectives. Maybe the efficacy of our prayers is linked to our actions, to our commitment to kindness and righteousness. Maybe it’s about approaching God with awe and humility, recognizing the abundance of divine love.

Ultimately, the Midrash leaves us with a powerful message: the path to connection with the Divine is multifaceted. It involves prayer, yes, but also repentance, righteous action, and a deep awareness of God's unwavering love and faithfulness. And perhaps, just perhaps, that’s the key to ensuring that our prayers are always heard.
