"With feelings of great weariness I arose to engage in the work. Before me lay new, polished shears, which I commenced using. At once my feelings of weariness and discouragement left me; the shears seemed to cut with hardly an effort on my part, and I cut out garment after garment with comparative ease. 2T 11.4"
"I can do all things through Christ which strengtheneth me."
Both passages deal with receiving strength from God to accomplish a task. The EGW passage describes physical weariness overcome, while the Bible verse is a general statement of empowerment through Christ.
