The world will get darker. In the natural, the attack was our HEALTH, specifically our immune systems (weak). In the Spiritual, it is our soul (Mind, emotions, and will). BUILD UP in BOTH AREAS ; for it matters what one thinks and places our FAITH, BE THE LIGHT.

However, get wisdom and understanding:

Understanding that some things in the building (our soul) must be rooted out, pulled down, destroyed and thrown down in order to build and plant. (Ps. 127:1) (Eccl.3:3) (1 Co:3:9) (Heb. 11:10) (Jeremiah 1:10).

As we read the book of Jude and focus on verses 17-23 we must build ourselves up:

17 But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ;

18 How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts.

19 These be they who separate themselves, sensual, having not the Spirit.

20 But ye, beloved, building up yourselves on your most holy faith, praying in the Holy Ghost,

21 Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.

22 And of some have compassion, making a difference:

23 And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh.

24 Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,

25 To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen.
