Luke 22:32 But I have prayed for thee, that thy faith fail not: and when thou art converted (strepho), strengthen (link -sterizo) thy brethren.
Even though Peter in the whirlwind of the crucifixion times, denied Christ several times, he stood up strengthened on the day of Pentecost after receiving the gift from God of holy spirit and delivered one of the boldest sermons in the history of mankind. Peter delivered that sermon. No one coerced him. He boldly stood up with assurance of what had happened and he was to impart it to his brethren.
Paul, later in the book of Romans, Paul displays this same calling.
Romans 1:11 For I long (epipitheo- earnestly desire) to see you, that I may impart unto you some spiritual gift (charisma), to the end ye may be established ;
To strengthen people, means laying out the truth before people. It is helping them see the same reassurance God provides to all who believe, that of holy spirit. In each of our lives, the risen Christ rests within our spirit with great potential. It becomes dynamic when the individual realizes his strength to accomplish his own unique great things for God.
Romans 16:25-27 Now to Him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery (Colossians 1:27), which was kept secret since the world began, But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith: To God only wise, be glory through Jesus Christ for ever. Amen.
