Philippians 4 tells us that gratitude in the present moves us out of anxiety about the future.
Rejoice in the Lord always. I will say it again: Rejoice! Let your gentleness be evident to all. The Lord is near. Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
Philippians 4:4-7
Rejoice in the Lord all day, every day. Don’t fret or worry. Instead shape your worries into prayers, letting God know your concerns, and before you know it, a sense of God’s wholeness will come and settle you.
