Let us go directly to the words of Jesus our Lord, in Matthew 7:21-27 He said whoever hears his sayings and does them, He (Jesus) likens that person to a wise man who built his house on a rock. And the person who does not do them, will be like a foolish man who built his house on the sand.
Jesus is the model in putting God's words into practice.But as you and I learned putting God's words into practice is not easy. Why ? because we inherited a sinful nature from our parents who also got them from Adam and Eve. We therefore need a new nature. II Corinthians 5:17 says, therefore if anyone is in Christ, he is a new creation,the new has come.
Next question, how can we be in Christ ?by responding to God's call to come to Him through the guidance of the Holy Spirit.
