"“I have words of encouragement for you, my brethren. We are to move forward in faith and hope, expecting large things from God. The enemy will seek in every way to hinder the efforts that are being made to advance the truth, but in the strength of the Lord you may gain success. Let no discouraging words be spoken, but only such words as will tend to strengthen and sustain your fellow workers.... 9T 8.2"
"I can do all things through Christ which strengtheneth me."
Both passages emphasize strength and ability coming from a divine source to accomplish tasks.
"And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching."
Both passages encourage mutual support and encouragement among believers.
