A person can humbly and prayerfully seek the Lord with a desire to serve the Lord and reach the lost. God will manifest gifts in a person's life for ministry to the lost and to the church. If that person ever stops praying or gets lifted up in his own spirit, the Spirit will leave him and he may try to manifest the gifts and fail, and then fake the gifts and then fall into sin.
Galatians 6:14 KJV
14 But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.
