I hesitate to use the above title because I have only heard that phrase misused, either by taking God's name in vain, (God says no, Dt. 5:11) or by using it to double down on truth telling. (Jesus says no, Mt.5:34) And it actually decreases the value of one's word. It is like saying, this time I am telling the truth! But the reason I think the title is appropriate is because we have been studying the minor prophets, and the prophets were not only unflinching in their messages from God to the people, but also honest with their own messages to God. Our most recent Bible studies have been on Jeremiah and Lamentations. None of the prophets were considered the life of the party, more like the death of it, but Jeremiah got to be the party pooper at a time of Judah's peace and prosperity. Those are good things. But it was also a time of hypocrisy that God finds detestable, outward observance of festivals and offerings while oppressing the weak and perverting justice. Those are bad things. Their religious rites and rules could not remove their wrongs and the ramifications. Their sacrifices stunk.
Jeremiah's message of the coming destruction of Jerusalem was extremely unwelcome. At best, the people ignored him, at worst, they tried to kill him. However, being less popular than sewage among his fellow Jews, gave Jeremiah time alone to pour out his honest sorrow to God--to lament. Often, as in many of the Psalms, the lament is followed by a statement of trust in God. I looked at the poems I have written in the year since Tracy died and found that 10 of the 12 include some form of "but God". In one poem, I remember not feeling the expression of trust I wrote, but truth is truth regardless of how I feel, so even that statement was honest to God.
There is often pressure from well meaning Christians to "fake fine" or rush through sorrow. They feel honest expression of our confusion or disappointment with God's plan is a poor testimony for a believer. But God is not a believer in shallow spirituality, that is one of the reasons Judah was being judged. Slapping a scriptural bandaid over a deep sorrow shows unfeeling faith to the suffering saint and unreal faith to the watching world. I need wisdom to know when, and to whom, I share my deepest sorrows, but I should always be honest to God.
