Psalms 107, 116, 118
The Lord will never stop dealing with those He loves, and is faithful to both discipline and bless them as He sees fit. We are to render thanks and praise to Him at all times, whether we are being blessed or humbled by the Lord, because everything He does is good, even though not always pleasant. The Lord hears our prayers and petitions, and we love Him for Who He is, and all He has done. He rescues us time after time, and preserves us until the day of His choosing.
The lovingkindness and mercy of the Lord is forever. As the psalmist says in 118:8-9, it is always better to take refuge in the Lord, rather than trusting in ourselves, in other men, or even in governments, or power kings.
