You become what you give your attention to.

As he passed alongside the Sea of Galilee, he saw Simon and Andrew, Simon’s brother, casting a net into the sea  — for they were fishermen. “Follow me,” Jesus told them, “and I will make you fish for people.” Immediately they left their nets and followed him. Going on a little farther, he saw James the son of Zebedee and his brother John in a boat putting their nets in order. Immediately he called them, and they left their father Zebedee in the boat with the hired men and followed him.

Mark 1:16-20
 

Discipleship is the lifelong journey of being changed by, following, and becoming more like Jesus.

 

For those he foreknew he also predestined to be conformed to the image of his Son, so that he would be the firstborn among many brothers and sisters.

Romans 8:29
 

We all, with unveiled faces, are looking as in a mirror at the glory of the Lord and are being transformed into the same image from glory to glory; this is from the Lord who is the Spirit.

2 Corinthians 3:18
 

I am sure of this, that he who started a good work in you will carry it on to completion until the day of Christ Jesus.

Philippians 1:6
 

This messy and grace-driven process happens best through the mutual sharing of our lives.

For you yourselves know, brothers and sisters, that our visit with you was not without result. On the contrary, after we had previously suffered and were treated outrageously in Philippi, as you know, we were emboldened by our God to speak the gospel of God to you in spite of great opposition. For our exhortation didn’t come from error or impurity or an intent to deceive. Instead, just as we have been approved by God to be entrusted with the gospel, so we speak, not to please people, but rather God, who examines our hearts. For we never used flattering speech, as you know, or had greedy motives  — God is our witness  —  and we didn’t seek glory from people, either from you or from others. Although we could have been a burden as Christ’s apostles, instead we were gentle among you, as a nurse nurtures her own children. We cared so much for you that we were pleased to share with you not only the gospel of God but also our own lives, because you had become dear to us. For you remember our labor and hardship, brothers and sisters. Working night and day so that we would not burden any of you, we preached God’s gospel to you. You are witnesses, and so is God, of how devoutly, righteously, and blamelessly we conducted ourselves with you believers. As you know, like a father with his own children, we encouraged, comforted, and implored each one of you to walk worthy of God, who calls you into his own kingdom and glory.

1 Thessalonians 2:1-12
 

The Great Commandment at it’s heart and the Great Commission as its trajectory

And one of them, an expert in the law, asked a question to test him: “Teacher, which command in the law is the greatest?” He said to him, “Love the Lord your God with all your heart, with all your soul, and with all your mind. This is the greatest and most important command. The second is like it: Love your neighbor as yourself. All the Law and the Prophets depend on these two commands.”

Matthew 22:35-40
 

Dear friends, let us love one another, because love is from God, and everyone who loves has been born of God and knows God. The one who does not love does not know God, because God is love. God’s love was revealed among us in this way: God sent his one and only Son into the world so that we might live through him. Love consists in this: not that we loved God, but that he loved us and sent his Son to be the atoning sacrifice for our sins. Dear friends, if God loved us in this way, we also must love one another.

1 John 4:7-11
 

Jesus came near and said to them, “All authority has been given to me in heaven and on earth. Go, therefore, and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe everything I have commanded you. And remember, I am with you always, to the end of the age.”

Matthew 28:18-20
