“Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forward to those things which are before,” (Philippians 3:13)

When the great Apostle Paul said the above, he was still under training.
The great Revivalist Elijah who shut up the heavens for three and half years, underwent further training at the brook Cherith and at Zarephat before the mount Carmel experience.
Whatever the Lord is taking you through now is training for something ahead. Elijah pulled upon the Brook and Zarepath trainings to stand victorious at Carmel. You will need the experience, for all things work together for good to them that love God, to them that are the called according to His purpose! (Romans 8:28)
It may be through the valley of the shadow of death, or high up on the mountain of success, He is not only with you, His grace is also with you and will sufficiently see you through!
So even as you are doing the work of the Lord, you are still undergoing training! Don’t be weary of studying.
Rather, “Study to show thyself approved to God, a workman that needeth not to be ashamed, rightly dividing the word of truth.” (2 Timothy 2:15).
