One of my favorite morning scripture is Psalm 118:24. I love the second stanza, "We will rejoice and be glad in it."
Isaiah 50:4 is also a powerful morning scripture where it states, "Morning by morning he wakens me.." The Lord is responsible for waking us up every morning, something we must give thanks for every day.
And don't forget Psalm 30:5: "Weeping may last through the night, but joy comes with the morning." Each morning is a joyous morning, regardless of our circumstances. Take a look at it this way, in the night we cry out to God in prayer and in the morning, we rejoice.
