Today's verses are Mark 4:16,17. "And these are the ones sown on rocky ground: the ones who, when they heard the word, immediately receive it with joy. And they have no root in themselves, but endure for a while; the, when tribulation or persecution arise on account of the word, immediately they fall away." Here Jesus is addressing the second soil, the second kind of human heart. When the seed of the Word of God comes into it, it is received immediately and with joy. It is a faith that is primarily birthed in emotion.
Please don't misunderstand. Emotions are good. God created them. They are gifts from him. The emotion Jesus reveals here, joy, is a wonderful emotion that does accompany faith in Christ. Galatians 5:22 says, "For the fruit of the Spirit is love, JOY..." But to receive the Word of God, to believe in Jesus solely with emotions and joy is a dangerous kind of faith.
Why? Because when tribulation and persecution arise because of your belief in and commitment to God's Word, an emotional faith cannot last. Note Jesus said WHEN tribulation and persecution come, not IF. They most certainly come to every follower of Jesus, especially if you believe unabashedly in the veracity of God's Word. The world hates truth. As they persecuted and killed the Word mad flesh, Jesus, so will his followers be similarly persecuted. The pupil is not greater than the master. If it happened to Jesus it will happen to us.
The mere emotional faith has no roots. Faith must find its roots deep in our spirits which then gives life to emotions. Our joy in Christ is the fruit of deep roots in our relationship with Jesus and his Word in our spirit. A shallow faith, only rooted in emotions, cannot withstand the trials, tribulations and persecutions that inevitably come to believers, especially when we hold tenaciously to the truth of God's Word.
We all want our faiths to have emotions. But we don't want our faiths to be rooted solely in emotions. That's the second kind of soil, the second kind of human heart, Jesus is examining here.
It's a faith than cannot last.
