| Luke 18:1Amplified Bible - Classic EditionALSO [Jesus] told them a parable to the effect that they ought always to pray and not to turn coward (faint, lose heart, and give up).See the chapter | 
Epaphras, who is one of yourselves, a servant of Christ Jesus, sends you greetings. [He is] always striving for you earnestly in his prayers, [pleading] that you may [as persons of ripe character and clear conviction] stand firm and mature [in spiritual growth], convinced and fully assured in everything willed by God.
But those who wait for the Lord [who expect, look for, and hope in Him] shall change and renew their strength and power; they shall lift their wings and mount up [close to God] as eagles [mount up to the sun]; they shall run and not be weary, they shall walk and not faint or become tired. [Heb. 12:1-3.]
