If you run around the soccer field for 90 minutes, you tend to sweat a lot. When you sweat excessively, your body loses much of its natural salt. Without salt in your body, you cannot stay hydrated. Being “salty” is an important part of being able to compete at a high level.
In the same respect, without a relationship with Jesus, you cannot absorb and learn from His Word. Learning God’s ways by reading the Bible will impact your approach to competition, but not until you give your life fully to God and accept what His Son did for you on the cross.
