Following Jesus' teachings (John 8:31-32)
We must be obedient children and doers of the Word. Obedience is the supreme test of faith in God (1 Samuel 28:18), and Jesus is the perfect example of obedience as He lived a life on earth of complete obedience to the Father even to the point of death (Philippians 2:6-8). A crucial sign of being a disciple is to exercise forgiveness and seeking restauration of relationships. Then Peter came to Jesus and asked, “Lord, how many times shall I forgive my brother or sister who sins against me? Up to seven times?” Jesus answered, “I tell you, not seven times, but seventy-seven times (Matthew 18:21-22).
Fruitfulness (John 15:5-8)
Our job is not producing fruit. Our job is to abide in Christ, and if we do, the Holy Spirit will produce the fruit, and this fruit is the result of our obedience. As we become more obedient to the Lord and learn to walk in His ways, our lives will change. The biggest change will take place in our hearts, and the overflow of this will be new conduct (thoughts, words and actions) representative of that change. The change we seek is done from the inside out, through the power of the Holy Spirit. It isn’t something we can conjure up on our own.
Love for other disciples (John 13:34-35)
We are told that love of other believers is the evidence of our being a member of God's family (1 John 3:10). Love is defined and elaborated on in 1 Corinthians 13:1-13. These verses show us that love is not an emotion; it is action. We must be doing something and involved in the process. Furthermore, we are told to do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of the others (Philippians 2:3-4). The next verse really sums up what we are to do when it comes to everything in life: In your relationships with one another, have the same mindset as Christ Jesus. What a perfect example He is to us for everything we are to do in our Christian walk.
Evangelism - Making disciples of others (Matthew 28:18-20)
We are to share our faith and tell nonbelievers about the wonderful changes Jesus Christ has made in our lives. No matter what our maturity level in the Christian life, we have something to offer. Too often, we believe the lie from Satan that we don't really know enough or haven't been a Christian long enough to make a difference. Not true! Some of the most enthusiastic representatives of the Christian life are new believers who have just discovered the awesome love of God. They may not know a lot of Bible verses or the "accepted" way of saying things, but they have experienced the love of the living God, and that is exactly what we are to share. Followers of Jesus introduce others to Jesus. Andrew, Simon Peter’s brother, was one of the two who heard what John had said and who had followed Jesus. The first thing Andrew did was to find his brother Simon and tell him, “We have found the Messiah” (that is, the Christ). And he brought him to Jesus (John 1:40).
