Ps John is preaching on how we respond in difficult seasons.
Unhelpful ways are constantly asking why (can be an endless treadmill), bitterness, searching for the instant fix, ignoring reality, denial, letting the crisis become our identity.
He encourages us, like King David did, to:
How? We hear from God, come to Christ, be filled with the Holy Spirit, worship, prayer, and read the word of God.
