Your Baptism was the greatest event of your life and the basis for all the other great events in your life. However, many Christians are not aware of the "radical newness" of their baptismal life and the "immense, extraordinary richness and responsibility" of baptism (Lay Members of Christ's Faithful People, Pope John Paul II, 10, 61).
When we were baptized, we were baptized into Christ (Rm 6:3). The only experience which is even remotely like this is pregnancy, the time when a baby is inside the body of his mother. Imagine you could enter again into the womb of your mother (see Jn 3:4). What radical changes this would mean for you! Nevertheless, being baptized into Jesus has much more stupendous ramifications. Baptized into Jesus, we are in His death, burial, and resurrection and have the saving benefits of these events (Rm 6:3-5). In Jesus, there is no condemnation (Rm 8:1). We are redeemed, forgiven, and chosen (Eph 1:7, 11). We are "a chosen race, a royal priesthood, a holy nation" (1 Pt 2:9). We spend our lives learning how to walk, talk, think, feel, work, pray, hear, see, and love in Jesus. We live our Baptisms.
