In spite of the bad news we receive and in spite of the troubles and setbacks that seem to come our way, we need to set ourselves on this: keep trusting. Keep trusting God in Christ. Keep trusting God's promises; hang on to them for dear life. Fall, as we will, on God's grace to us in Jesus.
L.L. Barkat's thoughts on lament are helpful here. We need to pray and let out our true heart and thoughts to God. But we also need to reach that place in our hearts, minds and will to keep trusting God no matter what.
When we do then we have to let go. And I mean this as ongoing; we don't just trust God once and that resolves it; it must be a daily, ongoing trust. This is a trust in God that lets the outcome of our concerns be in God's hands, not in our own. Our place is to simply trust and obey God, obeying God's word and following God's leading through the Spirit and in community with his people. This won't always look pretty or feel good. Quite the contrary, as we see in many of the psalms.
Through thick and thin; times of discouragement and encouragement: we need to keep trusting God. Will we? And how will that be evident in how we live? What will it look like to really keep trusting God in our lives? What is the outcome?
