The cross has almost always been important symbol for Christians. Although controversial at first, because it seemed to focus so much on the violence done to Jesus, the cross soon became the most prominent way for Christians to announce themselves. Not simply a reminder of Christ's gruesome death, the cross is also a invitation to celebrate Jesus' triumph over death, and our assurance that death is not the end of Christian journey.
Displaying the cross publicly or personally should never be a condemnation of others, especially Jews, but a reminder to ourselves and others, that God came among us as human person who not only announced God's love for us in its fullness, but also handed himself over to death as a symbol of his total identification with us at every stage of our journey.
Although we might at times be too casual about it, signing ourselves with the cross is a powerful reminder of Jesus triumph of over sin and death and sign that Jesus, "Having disarmed the powers and authorities, ...made a public spectacle of them, triumphing over them by the cross." (Col 2:15)
Today, make the sign of the cross as you wake and ask for the grace to accept whatever the day brings.
