Question: is the prayer of serenity in the bible

Answer: No, Niebuhr, who first wrote the prayer for a sermon at Heath Evangelical Union Church in Heath, Massachusetts, used it widely in sermons as early as 1934 and first published it in 1951 in a magazine column. The prayer spread through Niebuhr's sermons and church groups in the 1930s and 1940s and was adopted and popularized by Alcoholics Anonymous and other twelve-step programs.
