God created us in his image and likeness. He wants us to share in his divine nature or his holiness: "Be holy because I, the LORD your God, am holy" (Lv 19:2), says the Lord. Holiness is, therefore, our common and primary call from God. All we do in our life should be at the service of this call to holiness. As God is calling us, we have the privilege of responding. There are many ways for us to respond. And God helps us by calling us again to different concrete styles of life, including marriage, religious life, ordained ministry, and other personal callings to serve Him in the Church or in the world. Normally, the reason someone seeks to follow the call to marriage, priesthood, religious life, etc. is to fulfill our primary vocation, the call to holiness.
