To have job security we should: (1) Increase our visibility in our industry. In whatever field we work or plan to work, let's establish contacts and relationships within it. Our goal should be to develop our skills so that we will get noticed and experience favour. When the time is right and we're ready, God will open doors for us. 'Surely, Lord, you bless the righteous; you surround them with your favour as with a shield' (Psalm 5:12 NIV).
(2) Maintain a divine perspective on our job. Let's remember that our work is only one of many channels God uses to provide for us. God miraculously provided for Elijah the prophet through a raven, a brook and a single mum with just enough food for one meal. God used four different streams to water the garden of Eden. When we have unmet needs or financial burdens, let's ask God to reveal different streams of provision to us.
And, let's stand on these two promises: 'My God will richly fill your every need in a glorious way through Christ Jesus' (Philippians 4:19 GWT). 'God has not given us a spirit of fear [of not being employed], but of power and of love and of a sound mind' (2 Timothy 1:7 NKJV).
So what now? Fear and faith are powerful forces that seek to rule your life (which includes your employment journey). One force takes you in the wrong direction, the other in the right direction. So, strengthen your faith by reading God's word, praying and entrusting the outcomes of your life to him.
