A book of promises to rely on whatever our circumstances in life When we are afraid, under pressure or worried, we can't help wishing that we could rely on something or someone that is stronger than ourselves. The promises of the Bible are as solid as a rock, and there are more than enough of them to meet every human need: from times of failure to bereavement, times of illness to loneliness. 'Every promise God has made has been kept; not one has failed', Joshua 23:14.
