Jesus did only those things that were placed in his mind by his Father. And he wants us to learn to live that way too. It's essential to fulfilling God's plan for our lives. The Bible says that Mary took time to listen to Jesus, but her sister Martha didn't because she was busy 'serving' (see Luke 10:40). We can get so busy serving the Lord that we lose our sensitivity to his voice and preoccupied with secondary things.
When Jesus met the two disciples on the road to Emmaus after his resurrection, they didn't recognise him. But he loved them, so 'he opened their minds so they could understand' (Luke 24:45 NIV).
We learn to hear from God by making time to hear from him. Fifteen times in the New Testament, Jesus said, 'He who has ears to hear, let him hear.' When we became a new creation in Jesus, we got new spiritual ears, but we must learn how to use them. Indeed, that must become one of the highest priorities in our lives. A newborn child has the ability to hear, but doesn't understand what he or she is hearing; understanding takes time, it takes learning, it takes attention, it takes intimacy with his or her parents.
So what now? God is always speaking to you but, like all people, you need to learn to listen and hear him. Make more time to be attentive to what he is saying to you. Plus, he is longing to teach you to hear him - thank him for that!
