Meditate on all the verses in Psalm 119...they speak life and hope when you may feel it difficult to do the right things .  The temptation of the "world" is so big, sometimes I feel as if  it is too big.
Well it may be too big for me, but it is not too big for God.  Psalm 119 gives me the strength, in each moment, to face any temptation that may come my way.  If I should fall, I know thru forgiveness I am lifted back up to go forward with Jesus.
You know God knew that we would have many, many troubles.  That is why He gave us His Word to help us;  not only to help us  "get by", but to help us prosper abundantly in everything we do...everything we do for God. 
We can find all joy, hope, love; everything; when we stay with God.  If you are feeling lost, or lonely; if your life has "lost its purpose",  find your answers through prayer and praying in God's word.  He will be there.  I hear all the time how God speaks to us through His word and I didn't always "really" believe that.  But looking back, I know it's true.  When I went to God with a humble, open heart, He spoke to me...through His word.  He really spoke to me.  And today, He spoke to me thorough Psalm 119.
When the world seems too big, maybe you are taking too big of bites; slow down and just feel each moment.  Hear your breath, feel your heart beat, listen in the silence for God to speak; He is always here for us.  He has promised this to us. Blessings for you.
