Self-control is biblical
But self-control is a biblical word and is linked with other qualities. ‘ .... for God gave us not a spirit of fear but of power and love and self-control’ (2 Timothy 1.7, ESV). The danger with this verse is that it turns us all into super self-confident, all-conquering, problem-solvers who never put a foot wrong and never have a stressful day. I have never been like that and have often had days where I fail to love the people I work with because they’ve stitched me up or let me down. As for a ‘spirit of power’, I have had days where I feel completely impotent and unable to see a way forward.
