Yes, I believe that following Jesus is a choice and each and everyone of us is free to make it.
Jesus said "Love the Lord your God with all your heart, all your soul and all your mind".
Love is an act of the will. It is entirely voluntarily. We can choose to love God or we can choose not to. We can choose to follow Him or reject Him. If love is not given out of our own free will, with full and deliberate consent on our part, then it is not true love at all.
Jesus asked Peter three times "do you love me?" and on each occasion he told Him that he did. Yet Peter continued to deny Him three times. "I don't know the man!" he exclaimed in Matthew 26:73-75.
Peter was forgiven, as was Thomas, but throughout the ministry of Jesus, some were called, they followed for a while, yet they chose to forsake Him. Not by accident, not by circumstances outside their control,but by wilful and deliberate choice.
Jesus taught His disciples the Lord's prayer. Not a prayer to be recited once, but a prayer that should be the model for all their prayers. "Lead us not into temptation and deliver us from evil". Jesus clearly believed that each and every one of His disciples was capable of falling away from Him: into temptation, the bondage of sin. Jesus instructed us to "take up our cross", not once, not twice, but daily and follow Him. It seems to me that Jesus is not so much interested in the commitment we made to Him many years ago, through an evangelical rally, through an "altar call", but quite simply, will we continue to follow Him today?
