Only in God will he find the truth and happiness he never stops searching for. However, we will always face many challenges and temptations. As a result, it requires us to rely on the love and mercy of God, and to put forth effort to resist and overcome temptations so that we can live in God as Paul's example: “I [he] live, no longer I [him], but Christ lives in me [him].” (cf. Gal 2:20)
St. Augustine, St. Aquinas, and Mystici Corporis Christi have taught us the twofold dimension of our relationship with Jesus as his mystical body. This relationship has its foundation is love because God himself is love. (cf. 1 John 4: 16)
