At the beginning of Ps. 42 there is a desperate longing for God as for water when one has been in a desert without it for a long time. The ongoing plight of refugees readily come to my mind. Those who cross the barren land through Mexico, risking their lives so desperate for safety, security and hope for better life in America.
Questions, real and rhetorical....The Psalmist cries out to God and lays bare his feelings of abandonment, he also goes inside himself and questions himself and answers with self talk....somewhat like an internal dialogue with God...and finally he comes out of the questioning and dialogue with his awareness that "what has worked/been in the past remains"....God is with him, he must trust in God's continued presence and guiding.
Yes, I have felt far from God at times in my life...I went to God in prayer, struggled with God in prayer and went to scripture, confessed what I know to be true..."when you feel far from God, God isn't the one who moved!" Confessed my weakness, asked God to help "Lord, I believe, help my unbelief". I also asked others for their prayers.
