What does the word of God have to say about young people?

From Christus Vivit, the Post-synodal Apostolic Exhortation of Pope Francis to the young people and the whole people of God

5. Let us draw upon some of the richness of the sacred Scriptures, since they often speak of young people and of how the Lord draws near to encounter them.

In the Old Testament

6. In an age when young people were not highly regarded, some texts show that God sees them differently. Joseph, for example, was one of the youngest of his family (cf. Gen 37:2-3), yet God showed him great things in dreams and when about twenty years old he outshone all his brothers in important affairs (cf. Gen 37-47). 

7. In Gideon, we see the frankness of young people, who are not used to sugar-coating reality. When told that the Lord was with him, he responded: “But if the Lord is with us, why then have all these things happened to us?” (Jg 6:13). God was not offended by that reproach, but went on to order him: “Go in this might of yours and deliver Israel!” (Jg 6:14). 

8. Samuel was still a young boy, yet the Lord spoke to him. Thanks to the advice of an adult, he opened his heart to hear God’s call: “Speak, Lord, for your servant is listening” (1 Sam 3:9-10). As a result, he became a great prophet who intervened at critical moments in the history of his country. King Saul was also young when the Lord called him to undertake his mission (cf. 1 Sam 9:2).

9. King David was chosen while still a boy. When the prophet Samuel was seeking the future king of Israel, a man offered as candidates his sons who were older and more experienced. Yet the prophet said that the chosen one was the young David, who was out tending the flock (cf. 1 Sam 16:6-13), for “man looks on the outward appearance, but the Lord looks on the heart” (v. 7). The glory of youth is in the heart, more than in physical strength or the impression given to others.

10. Solomon, when he had to succeed his father, felt lost and told God: “I am a mere youth, not knowing at all how to act” (1 Kg 3:7). Yet the audacity of youth moved him to ask God for wisdom and he devoted himself to his mission. Something similar happened to the prophet Jeremiah, called despite his youth to rouse his people. In his fear, he said: “Ah, Lord God! Truly I do not know how to speak, for I am only a youth” (Jer 1:6). But the Lord told him not to say that (cf. Jer 1:7), and added: “Do not be afraid of them, for I am with you to deliver you” (Jer 1:8). The devotion of the prophet Jeremiah to his mission shows what can happen when the brashness of youth is joined to the power of God.

11. A Jewish servant girl of the foreign commander Naaman intervened with faith and helped him to be cured of his illness (cf. 2 Kg 5:2-6). The young Ruth was a model of generosity in remaining beside her mother-in-law who had fallen on hard times (cf. Ru 1:1-18), yet she also showed boldness in getting ahead in life (cf. Ru 4:1-17).
