Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God;
Phil 4:7 and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.
Our hearts (attitudes, desires, trust and emotions), and minds (thoughts, memories, conscience, imaginations), need guarding because this is what comes under the severest pressure. Our only defence is the peace of God which acts as a fortress against all incoming troublesome thoughts and attitudes.
Mental health and emotional well-being come by relieving anxiety from our minds and hearts. This is achieved not through medication but every day through prayer. But this is not just prayer, because prayer on its own can be simply the pleadings of worry. Thanksgiving must be part of our prayer life and our all day speech. Complaining is the language of victims and is the fastest route to a negative mindset which in turn leads to our minds being ill at ease and depression. The person who takes pains to appreciate others and be grateful will find their hearts and minds in far better health than the prayer-less, cynical complainers. Following our prayers comes His peace.
His peace is totally unreasonable. There is no logical reason why we can be peaceful under dreadful circumstances, yet we are, because of His Presence upon us. This beautiful serenity pervades our hearts and minds with sanity and a bright perspective on whatever comes our way.
Cast all your cares upon Him!
Because He cares for you!
