PHILIPPIANS 4 : 6-9 "Do not be anxious or worried about anything, but in everything [every circumstance and situation] by prayer and petition with thanksgiving, continue to make your [specific] requests known to God. And the peace of God [that peace which reassures the heart, that peace] which transcends all understanding, [that peace which] stands guard over your hearts and your minds in Christ Jesus [is yours].Finally, believers, whatever is true, whatever is honorable and worthy of respect, whatever is right and confirmed by God’s word, whatever is pure and wholesome, whatever is lovely and brings peace, whatever is admirable and of good repute; if there is any excellence, if there is anything worthy of praise, think continually on these things [center your mind on them, and implant them in your heart]. The things which you have learned and received and heard and seen in me, practice these things [in daily life], and the God [who is the source] of peace and well-being will be with you."
1 PETER 5 : 7 "casting all your cares [all your anxieties, all your worries, and all your concerns, once and for all] on Him, for He cares about you [with deepest affection, and watches over you very carefully]."
