“Finally, my brethren, be strong in the Lord, and in the power of his might” Ephesians 6:10.
You know that every person can develop and strengthen himself in various aspects: physically, psychologically, intellectually, financially and etc. The Word of God encourages us to be strong in our Lord and to gain power which is not human, but spiritual. Achieving human goals is alright, but you will never be able to fulfill your calling from God if you rely on human strength, wisdom and talent. You will need inspiration from the Holy Spirit, His comfort and might during hardships and the grace of the God in your spiritual battles, which will be plenty.
