You will keep in perfect peace those whose minds are steadfast, because they trust in you.
In today’s world it can be difficult to gain peace of mind.
In fact it is a new industry, with coaches, books and podcasts, magazines and countless YouTube videos, telling you how to quieten your thoughts and take refuge from the daily grind.
Isaiah appears to have been ahead of the curve.
Over two and a half thousand years ago the Prophet was telling it like it is.
Trust in God and He will keep you in perfect peace.
To get the peace you need to have a mind – yetser – the thoughts and imagination being framed in a particular way – to be steadfast – samak – (only occ. 2 times in OT) to lean on, to lay on, to establish yourself on, to put yourself on, to rest on.
Think in the manner of God and you will have peace – shalom – peace in every sense, favour, friendship, be happy, because you trust – batach – you are bold and confident in, secure and sure in, to have confidence and hope in, God.
Peace of mind comes from keeping your thoughts as close to God as you can. In response He will bring you peace, and in that you can have perfect trust.
Chasing around in the world will not give us peace, being close to God, through reading the scriptures, spending time in prayer, being closer to his creation, however, will bring us the peace we definitely need.
