A rich young ruler was so deeply moved that as Christ was going on His way, he ran after Him, and kneeling at His feet, asked with sincerity and earnestness the question so important to his soul and to the soul of every human being, "Good Master, what shall I do that I may inherit eternal life?" 

Yes, not just the rich young ruler, but the question is to be understood by "every human being."  There is something we all must do in order to be saved. The first and greatest of all commandments is to love the Lord our God with all of the heart. Until we love God supremely we cannot be saved. Then the question is what must I do that I will love God with all I am and all I have, holding nothing back. There is only one way to do this, spend time beholding His glory which is His character.

Only those who will become co-workers with Christ, only those who will say, Lord, all I have and all I am is Thine, will be acknowledged as sons and daughters of God.

We cannot trust God with all we have and all we are until we know Him intimately. It would be very good for us to spend a thoughtful hour a day contemplating the life of Jesus. We are a forgetful people. We must day by day come back to the cross to remember what God has done for us. He does not give us grace for tomorrow, but only for today. Then by beholding His character daily we shall be transformed into His character every day. "We all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord." 2 Cor. 3:18.
