From Philippians 4:4-7
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 everything, 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.
Worry and stress can lead to an unguarded heart. Likewise, rejoicing in the Lord helps guard your heart. Paul tells us to rejoice in the Lord in all things. We are to rejoice and know that the Lord is near.  He is not distant or unknowing of your needs at anytime. With God near, what do we have to worry about? Who is greater than God?
Instead, we should confidently be thankful to God in everything, both what seem good and bad. Present your requests to God who is standing right next to you. Present them in a spirit of thanksgiving. Why would you be thankful if God was not going to take care of your request for you? Oh, but He is going to take care of it.Â
Living this way allows you to experience the transcending peace of God. This protects and guards our hearts from temptation, fear, and disobedience. Certainly as we live in this world we need our hearts to be guarded.
You speak of freedom; my hope is that this post saves others. In my learning’s, it seems that until we have faith and trust in God, we do not realize that we are in bondage from our own stress and anxieties.
