It is a paradox because you cant be alone because he is in you,yet sometimes we feel alone.The psalms are there to help us.Some times we pant like a deer because we are thirsty in a dry place,but fear not.It says "I was once young,yet now I am old,but I have never seen the righteous forsaken".Somtimes walking by faith and not sight is just that.No sight meaning our natural senses dont always do much,but our faith,even as a flickering wick,will not be snuffed out.Take care.
