"I can do all things through Christ who strengthens me" -Phillipians 4:13(my favorite scripture)
"And those that wait upon the Lord shall renew their strength;They shall mount on wings as eagles; they shall run and not be weary; they shall walk and not faint" -Isaiah 40:31
"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof." - Matthew 6:33-34
Usually, I select my favorite scriptures, depeding on what circumstances I go through. In other words, these may be my favorite scripture today, but it may be a different one tommorow.
"Consider it pure joy, my brothers, whenever you face trials of many kinds, because you know that the testing of your faith develops perseverance. Perseverance must finish its work so that you may be mature and complete, not lacking anything."James 1:2-4 - NIV "Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen. For what is seen is temporary, but what is unseen is eternal." - II Corinthians 4:16-18 - NIV
