Both Old and New Testament scriptures underscore the importance of loving God with all that we possess: body, soul (mind, will, and emotions), and spirit (Deut. 6:5-9 and Mark 12:28-31).
While we live in the world, we are commanded not to be “of” the world, because its spirit specifically targets and appeals to our fallen nature:
1 John 2:15-16 15 “Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. 16 For everything in the world — the cravings of sinful man (lust of the flesh), the lust of his eyes (Mammon, materialism, covetousness) and the boasting of what he has and does (pride of life)—comes not from the Father but from the world.”
James 4:4 “… don’t you know that friendship with the world is hatred toward God? Anyone who chooses to be a friend of the world becomes an enemy of God.”
