Absolutely. Where did this idea that "God is love" and "all you need is love" come from? I'm guessing Liberal Christianity and the "Social Gospel". Even if you only read the New Testament it's clear that the consequences of sin are dire. And general revelation in nature shows us the world is brutal. Thank God for salvation through faith in Christ alone. And completely underserved to boot. Eternal life and salvation as a free gift! Loving to the elect for sure, but for those not called by grace.... well that is humbling and awe inspiring to consider....

It comes from Gods word, the Church, and the actions of Christians. The NT is full of it besides this but here it is literally. But people distort the Gospel and today it seems people want to manipulate the Word to fit the culture.
1 Jo 4:8 NASB The one who does not love does not know God, for God is love.
And
1 Jo 4:16-17 NASB We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him. By this, love is perfected with us, so that we may have confidence in the day of judgment; because as He is, so also are we in this world.
