"You have been on a long, uphill journey, and your energy is almost spent. Though you have faltered at times, you have not let go of My hand. I am pleased with your desire to stay close to Me. There is one thing, however, that displeases me: your tendency to complain. You may talk to Me as must as you like about the difficulty of the path we are following. I understand better than anyone else the stresses and strains that have afflicted you. You can ventilate safely to Me, because talking with me tempers your thoughts and helps you see things from My perspective.
Complaining to others is another matter altogether. It opens the door to deadly sins such as self-pity and rage. Whenever you are tempted to grumble, come to Me and talk it out. As you open up to Me, I will put My thoughts in your mind and My song in your heart."
I was recently reminded that the devil is not omniscient. Unlike God, Satan does not know everything we are thinking and feeling. God knows the things that are bothering, burdening, and breaking our hearts, but Satan does not. He can only find those things out - and thus use them against us - once we say it aloud. Complaining not only hinders our ability to recognize the multitude of blessings that the Lord gives to us, but also gives Satan an easy in.
I have been learning lately that, while I may have many reasons to complain, that doesn't mean I should... especially not to other people. Rather, I should first bring my worries, problems, and heartbreaks to God in prayer. He is our safe place, our refuge, and our strength (Psalm 144). Then, as necessary, we can seek counsel and advice from others.
I have been reminded I should choose joy in spite of my circumstances, because I have every reason to be joyful in the presence of the King. And so do you.
