" faith has tasted the glory of God in Christ and treasures it enough that the fullness of it is worth waiting for and suffering for. Faith has seen the truth that part of Christ's glory is his trustworthiness. Therefore, faith can cast itself on the promise of Christ and trust that the fullness of glory and the fullness of joy will surely come. "
