The joy of the Lord is my strength.  My God is strong in me even when I am puny. When I feel ineffective and useless I need to get my eyes back on the One that hears every prayer and provides for everything I need.  I am strengthened when I remember the wonderful promises in God’s Word concerning those that belong to Christ. 

Joy Needs Never to Flee

There never needs to be a time, when joy flees out of sight.
Keep God in mind, and in Him you find delight.
Troubles come and trials are faced, but when you remember God’s there;
Fear, doubts, and worry are replaced with the joy that He with you shares.
The day may be dark all around, but in the light of love.
You walk on higher ground, with and in the joyful presence of God above.
With your eyes on the goal ahead, with a joyful step make your way.
For when you are by the Spirit led, there is sunshine in your day.
Joy walks with and ahead of you; with strength that overflows.
Joy leads and guides you through, wherever you need to go.
Rejoice in the Lord all the time, again I say rejoice.
Lift up Jesus name and find, joy is shared by the sound of your voice/

Philippians 4:4
Rejoice in the Lord alway: and again I say, Rejoice.
