Zephaniah 3:17 is a wonderfully reassuring Scripture for each child of God to meditate on, lay hold of and ask of God to make it real. It is one that can be turned to immediately in the midst of a hard situation. The verse in the King James Version has been set to music and I would suggest that you learn to sing it for it will fill your heart with gladness and cause you to focus on God's love instead of circumstances.

The New American Standard Version of 3:17 reads, "The Lord your God is in your midst, A victorious warrior (a warrior who saves).
He will exult over you with joy,
He will be quiet in His love, (Revised Standard Bible says, 'renew you in His love') He will rejoice over you with shouts of joy."
(The parentheses are margin explanations.)

Who is this who exults over you with joy, who rejoices and shouts with joy? It is Yahweh! The Almighty God! Not from afar, but in your midst!
Imagine!

This is cause for the child of God to reverence Him above all things, to trust completely, to seek to do His will and to cleave to Him in joyous fellowship placing all of life's earthly circumstances in His hands.
Therefore, in this we can be '...Anxious for nothing...' Philippians 4:6

This then is a child at rest in his soul. The rest of God that He bids us to enter into. For here is where fellowship with God takes place -- where all is peace and joy -- '...Hidden with Christ in God.' Colossians 3:3 Colossians 3:3-4 in The Amplified Bible reads, "For [as far as this world is concerned] you have died, and your [new, real] life is hidden with Christ in God. When Christ, Who is our life appears, then you also will appear with Him in [the splendor of His] glory."

We are saved, a new creation--sanctified, separated from this world--a people for God's own possession,. He is in our midst, rejoicing in His love over His own.

Therefore,
"...Let the peace (soul harmony which comes) from Christ rule (act as umpire
continually) in your hearts [deciding and settling with finality all questions that arise in your minds, in that peaceful state] to which as [members of Christ's] one body you were also called [to live]. And be thankful (appreciative), [giving praise to God always,] Colossians 3:15 The Amplified Bible

To Almighty God; Father, Son and Holy Spirit, with thanksgiving, we give praise, honor and glory, now and forever. Amen
