Phil. 4:6 Do not fret or have any anxiety about anything, but in every circumstance and in everything, by prayer and petition (definite requests), with thanksgiving, continue to make your wants known to God.
7 And God’s peace which transcends all understanding shall garrison and mount guard over your hearts and minds in Christ Jesus. Philippians (Amplified Version)

John 10:1 Jesus said to the Pharisees, “Listen to this eternal truth: The person who sneaks over the wall to enter into the sheep pen, rather than coming through the gate, reveals himself as a thief coming to steal. 2 But the true Shepherd walks right up to the gate, 3 and because the gatekeeper knows who he is, he opens the gate to let him in. And the sheep recognize the voice of the true Shepherd, for he calls his own by name and leads them out, for they belong to him. 4 And when he has brought out all his sheep, he walks ahead of them and they will follow him, for they are familiar with his voice. 5 But they will run away from strangers and never follow them because they know it’s the voice of a stranger.” 6 Jesus told the Pharisees this parable even though they didn’t understand a word of what he meant.
7 So Jesus went over it again, “I speak to you eternal truth: I am the Gate for the flock. 8 All those who broke in before me are thieves who came to steal, but the sheep never listened to them. 9 I am the Gateway. To enter through me is to experience life, freedom, and satisfaction. 10 A thief has only one thing in mind—he wants to steal, slaughter, and destroy. But I have come to give you everything in abundance, more than you expect —life in its fullness until you overflow! 11 I am the Good Shepherd who lays down my life as a sacrifice for the sheep. 12–13 But the worker who serves only for wages is not a real shepherd. Because he has no heart for the sheep he will run away and abandon them when he sees the wolf coming. And then the wolf mauls the sheep, drags them off, and scatters them.
14 “I alone am the Good Shepherd, and I know those whose hearts are mine, for they recognize me and know me, 15 just as my Father knows my heart and I know my Father’s heart. I am ready to give my life for the sheep. (Passion Translation)
