When God is the one who made the foundations of the earth, why should we be anxious over anything. He is all powerful and almighty. Who could be bigger or greater or stronger than God.
Psalm 104 1 Bless Jehovah, O my soul. O Jehovah my God, thou art very great; Thou art clothed with honor and majesty: 2 Who coverest thyself with light as with a garment; Who stretchest out the heavens like a curtain; 3 Who layeth the beams of his chambers in the waters; Who maketh the clouds his chariot; Who walketh upon the wings of the wind; 4 Who maketh winds his messengers; Flames of fire his ministers; 5 Who laid the foundations of the earth, That it should not be moved for ever.
