From Single Men: Carry The Colors:

Resolve is the faith that keeps you moving even when the fog of battle overwhelms you. Jesus had resolve in going to the Cross. Paul had resolve in pressing on toward the goal. Resolve looks ahead. Resolve is clear-eyed, level-headed, sober-thinking. It is fueled by the burning reality that service in this life is the only battle that matters, and that God himself has placed you in it. So spend it all here. As the famous missionary motto proclaims, "No retreat, no surrender, no reserve."

And the writer goes on to say:

God made you a man for a purpose. Inherent in your masculinity is a call to step forward, not simply to take the flag, but first to ask for it and reach toward it. Masculinity is the raw material of leadership in God's government, but you don't need to wait for a tap on the shoulder to express your innate leadership call. You can lead by influence and example. If you are not being trained to lead, get your Bible out and train yourself! Your Christian single sisters are always looking for men to step out in leadership in areas such as purity, discernment, decisions, and godly conversation.
