In other discussions about this topic on this site I’ve seen passages used in support of seeking a sign that mention signs in the context of faith but those signs are freely given by God through the apostles; when demanded, e.g. by those of Jesus’ fellow Israelites who rejected him, it was rebuffed by Jesus himself (look up “the sign of Jonah” in the Bible). And other passages about God asking the Jews to test him in his promises by tithing as they were required by the Law are out of context of this discussion, and arguably different—there God is basically begging them to believe him and his promise, that they should willingly give up some of their livelihood, a crazy thing in human wisdom, because God has promised to bless them over and above what they gave up (the tenth or tithe). Anyone arguing that we are to put God to the test in the context of this question needs to make sure to use such passages in context, and from what I see in the Bible, they do not support the idea of such a seeker’s prayer being Biblical. Seeking is good (there is no better thing than to find Jesus) but it must be on God’s terms, not ours. Faith is key.
