"Begin with the end in mind" (e.g. envision what you want in the future so that you know concretely what to make a reality) aligns all positions of personal expectation and state of mind to centralize on the nature of God. Clearing my mind would be futal if I did not open it and fill it with His.
The Bible-way to a healthy mind is this, “Let this mind be in you, which was also in Christ Jesus.” If you have the mind of Christ, worry will be offset by trust, enmity by love, and fear by faith.
Daily Prayer
Fears sometimes seem as if they would overwhelm me, Lord Jesus, but then I remember Your gift of power, love, and a healthy mind. Thank You for the promise of healing and love, as I keep my mind on You, my beloved Lord.
2TI 1:7 HCSB
For God has not given us a spirit of fearfulness, but one of power, love, and sound judgment.
