Few people would dispute the fact that the book of Ecclesiastes is the most depressing book of the Bible. It begins: "Vanity of vanities, says Qoheleth, vanity of vanities! All things are vanity!" (Eccl 1:2) It ends: "Vanity of vanities, says Qoheleth, all things are vanity!" (Eccl 12:8) Ecclesiastes depicts the utter emptiness and hopelessness of life without Christ. However, we who are baptized into Christ have been "delivered from the futile way of life" (1 Pt 1:18) to live the truly new (see 2 Cor 5:17) and absolutely abundant life (Jn 10:10).
If this is true, why are we Christians sometimes as depressed as anyone else? There are several explanations for post-Christ, post-baptismal depression. Nevertheless, no matter what the circumstances, to change from vanity to fullness we must renew our Baptisms and "stir into flame the gift of God" (2 Tm 1:6).
Right now, renew your baptismal promises by rejecting Satan, all his works, and all his empty promises. Express your total faith in God the Father, God the Son, and God the Holy Spirit. Bless yourself with the holy water which reminds us of our Baptism. Baptized into Jesus, our lives are not vain; rather, they are lives of "justice, peace, and the joy that is given by the Holy Spirit" (Rm 14:17).
