Come to me, all you who labor and are burdened, and I will give you rest. (Mt. 28:11)
For the Christian, our ultimate hope must be Jesus Christ and the Gospel. He came into the world to redeem us, to open the possibility of eternal life in perfect love and joy with God. But our lives are lived in the world. The challenge is not to hide from the world; we feel compelled to work for truth and justice and to let others know of the Lord's love and desire for them to live in faith, hope and love. This work begins with our witness, how we live each day and each moment.
In order for us to truly live in the world, but not of the world, we need to remain united to the Lord. We need to constantly be listening for His voice and seeking to live out his will for us. We need to follow Jesus' example in the Gospels and constantly take time to spend with Him in prayer--not just liturgical, communal prayer (but that is a must also), but time in quiet, to be in His presence and to simple be-to rest.
In the chaos of the day ahead, look for some time when you can just be in the quiet, whether it be 5 or 10 or 15 minutes. Force it into your schedule if have to. This will keep you rooted and focused on what matters in life.
