Why is the testimony of God important for Christians?

The testimony of God is crucial for Christians because it provides the foundation for understanding the means of salvation and eternal life. According to 1 John 5:11-12, God has given us eternal life through His Son, and this testimony articulates the essential truth that whoever has the Son has life. The clarity and simplicity of this message offer assurance to believers that their faith is based on God's trustworthy promise. Understanding God's testimony empowers believers to live in the confidence of their salvation, knowing that it is not dependent on their actions but on the unchanging promise of God.
