18 We know that whoever is born of God doesn’t sin, but he who was born of God keeps himself, and the evil one doesn’t touch him. 19 We know that we are of God, and the whole world lies in the power of the evil one. 20 We know that the Son of God has come and has given us an understanding, that we know him who is true; and we are in him who is true, in his Son Jesus Christ. This is the true God and eternal life. 21 Little children, keep yourselves from idols.

In Genesis, humanity fell when they listened to the serpent and doubted God's goodness, which plunged the human race into spiritual darkness (Genesis 3:1-6). John acknowledges this tragic reality by stating that the whole world now lies in the power of the evil one (1 John 5:19). Yet, the Gospel is the glorious announcement that God did not leave us in this helpless condition. Instead, the Father sent His own Son to break the power of…

Deep beneath the ocean surface, where the water pressure is immense enough to crush steel, saturation divers live and work inside a specialized pressurized habitat. Outside this steel capsule, the freezing water is pitch-black and deadly, capable of ending a human life in a fraction of a second.

They do not survive by fighting the ocean with their own physical strength; they survive because they are…
