June 2025 - Advanced Topics in Tech and Faith

In an age when artificial intelligence powers everything from healthcare diagnostics to language translation, understanding how deep learning works is a valuable and sought-after skill. For Christians in tech, it’s not just about mastering tools—it’s about using that mastery to serve others and glorify God with excellence.

One of the most powerful frameworks for deep learning today is TensorFlow, an open-source library developed by Google. Whether you’re just starting out or expanding your machine learning toolkit, TensorFlow offers the flexibility and scalability needed to build models that can learn from data and make intelligent decisions.

What Is TensorFlow?

At its core, TensorFlow is a comprehensive platform for building and training machine learning models. It’s especially well-suited for neural networks and deep learning due to its high-level APIs and integration with GPU acceleration.

The name “TensorFlow” comes from the way data is represented—as tensors, or multi-dimensional arrays—and how it “flows” through a computational graph.

Why Learn TensorFlow?

TensorFlow is not just for researchers—it’s used in real-world applications like:

  • Image recognition and computer vision
  • Natural language processing (NLP)
  • Speech recognition
  • Time series forecasting
  • Health diagnostics
  • And more…

As Christians with a heart to serve, imagine building tools that can help the visually impaired “see” the world through object detection, or help pastors translate their sermons across languages to reach more people. The possibilities are vast.

Getting Started: A Simple Neural Network

Here’s a quick look at how to build a basic neural network using TensorFlow and its high-level API, Keras:

import tensorflow as tf
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Dense

# Example: Simple model for binary classification
model = Sequential([
    Dense(16, activation='relu', input_shape=(10,)),
    Dense(8, activation='relu'),
    Dense(1, activation='sigmoid')
])

model.compile(optimizer='adam', loss='binary_crossentropy', metrics=['accuracy'])

# Suppose X_train and y_train are your training data and labels
# model.fit(X_train, y_train, epochs=10, batch_size=32)

This basic model takes in 10 input features, processes them through two hidden layers, and outputs a binary prediction.

Walking in Faith with AI

It can be tempting to view these tools as purely technical or even as replacements for human wisdom. But as we dive deeper into AI, we should continually ask: How can this technology reflect the love, creativity, and compassion of our Creator?

Paul writes in 1 Corinthians 10:31:“So whether you eat or drink or whatever you do, do it all for the glory of God.”

That includes code. That includes data. That includes models that learn.

Final Thoughts

TensorFlow isn’t just a tool—it’s an opportunity. An opportunity to build applications that are smart, helpful, and rooted in purpose. As we gain deeper technical skills, may we also grow in wisdom, using these gifts to serve our communities and spread the light of Christ in a digital world.
