The cruelest and most difficult battles of existence are fought in the spirit, the place from where communication with the invisible and spiritual is presented; it needs care and attention based on the eternal, it is strengthened through experiences that are neither palpable nor physically demonstrable.

A beautiful analogy is given when the eagle teaches his eaglet to fly, through the knowledge and differentiation of the winds; it begins with destroying its nest, to then force it to fall from the cliff. The inexperienced royal bird considers that he will die; but the mother eagle rescues him by receiving him on top of her, thus freeing him from his imminent fall onto the rocks.

Again and again, she throws him into the void, until the eaglet can move through the air and his real nature of freedom is manifested; to know the heights, soaring in flight.

Isaiah 40:29-31 NKJV

29 He gives power to the weak, and to those who have no might He increases strength.
30 Even the youths shall faint and be weary, and the young men shall utterly fall,
31 But those who wait on the Lord shall renew their strength; they shall mount up with wings like eagles, they shall run and not be weary, they shall walk and not faint.

Psalm 55:22 NKJV

22 Cast your burden on the Lord, and He shall sustain you; He shall never permit the righteous to be moved.

2 Corinthians 3:17-18 NKJV

17 Now the Lord is the Spirit; and where the Spirit of the Lord is, there is liberty. 18 But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord.
