"Surely, Christians never struggle with feelings of depression, loneliness, and hopelessness."
Don't call me, Shirley, and yes we can; being a Christian does not remove one from the world and the things of it. Jesus felt sadness, loneliness, loss, and despair. " He is despised and rejected of men; a man of sorrows, and acquainted with grief:" Isaiah 53:3. How can we expect to escape similar trials, and tribulations?
We can't. Sometimes the darkness, pain, suffering and feelings of worthlessness come from Satan; perhaps we are about to do great works for the Lord, and he plants the seeds of doubt and depression in us, to stop our mission.
The paths we choose in life, can take us to destinations that on second thought we would have rather avoided. We cannot go back, and turn right instead of left, we must turn our collars up, put our heads down, and face the storm we have turned into, a storm of our own making.
He calms the storm, So that its waves are still. Psalm 107:29
All we can do is call on Him, and pray for faith, guidance, and protection. The answer may not come quickly, or be the one you want, but know that God is there, in your corner, to guide you through the storms of life. Set your course to the light, and leave the darkness behind.
Answer me speedily, O Lord; My spirit fails! Do not hide Your face from me, Lest I be like those who go down into the pit. Cause me to hear Your lovingkindness in the morning, For in You do I trust; Cause me to know the way in which I should walk, For I lift up my soul to You.
