There are many stories in the Bible of people who stepped across the line. The tasks given to them by God required courage and faith, and with God's strength they carried out His purposes. Our heroes go up against all logic, against oppression, against faithlessness, against all odds, against injustice and against accusers.
They provide examples of what it can be to follow God into places which might not appear 'natural' to us or uncomfortable. So perhaps, if they can do it, so can we. Each Sunday we will learn something from these men and women of old.
