Then it is too late to go back.

There are many people in mid-life, bound now in the chains of evil companionships, who would give all they have for the sweet delights and pure pleasures of friendship which once might have been theirs, which in youth reached out to them in vain white hands of importunity and blessing.

But it is too late; the door is shut.
So it is with the opportunities of doing good to others, comforting, helping, cheering, lightening burdens, giving gladness and joy.

We stand continually before open doors which we do not enter.

Ofttimes we shrink with timid feeling from the sweet ministry, holding back the sympathetic word or restraining ourselves from the doing of the gentle kindness, thinking our proffer of love might be unwelcome.
