8 For he who sows to his flesh will of the flesh reap corruption, but he who sows to the Spirit will of the Spirit reap everlasting life.
What you feed will lead. Whichever nature you feed the most in your life, flesh or spirit will determine which will dominate. When you are dominated by the spirit, God always leads you in triumph. The failures of many comes down to what is leading them. The choice is up to us based on which nature we feed the most.
