If you think of it, I would especially appreciate your prayers early in the morning, as this seems to typically be my hardest time of day. Of course, "hardest" still means other times of day can be "hard" too, so God, who works outside of human time anyway, will surely honor your prayer (and I welcome them) any time of the day!
In the morning, LORD, you hear my voice; in the morning I lay my requests before you and wait expectantly. - Psalm 5:3
Let the morning bring me word of your unfailing love, for I have put my trust in you. Show me the way I should go, for to you I lift up my soul.- Psalm 143:8
Because of the LORD’s great love we are not consumed, for his compassions never fail. They are new every morning; great is your faithfulness.
