A mature Christian "preaches" with his or her life.

Many times we try to talk people into accepting Jesus, but yet we fail to show them Jesus; we don't act any differently than the rest of the world, even though we claim to be saved. The world isn't looking for talk; it wants walk. Therefore, we, as Christians, must live differently: stop telling, and start showing.

Matthew 7:20 tells us how to recognize truly mature Christians: "by their fruit." Stop worrying about the outward show that you put on in front of your friends, and start developing the Fruit of the Spirit in your inner life (see Galatians 5:22-23). Then once you have learned to be kind, gentle, peaceful and joyful even during difficult circumstances, non-Christians will see you and say to themselves, "I want what you've got." Then, you will be able to share Jesus with them effectively.

We need to develop the Fruit of the Spirit in our lives. Interestingly, the first Fruit mentioned in Galatians 5:22-23 is "love." Furthermore, in John 13:35, Jesus said, "By this all men will know that you are my disciples, if you love one another." In other words, love ought to be the trademark of every believer.

It is by living a life of love that you make the world hungry and thirsty for the joy, kindness, patience, peace, and stability that you have. The world isn't reading the Bible; they're reading Christians like you. And if they don't like what they see in you, they're not going to want what you've got—Jesus.

Before you can love others, you must receive God's love for yourself, because you cannot give away something you don't have

God deeply and intimately loves you! His love for you is unconditional—no strings attached, and there is nothing that you can do to get God not to love you. Indeed, Romans 8:38-39 says that there is nothing that can ever separate us from God's love. Knowing that God loves you is central to your understanding of the Gospel, for the entire Gospel is based on God's love (See John 3:16, Romans 5:8, 1 John 3:16, 1 John 4:9-10). The good news is that God hasn't withheld His love from us; instead, God has poured out his love into our hearts (Romans 5:5). But what do we do with that love? We know God loves us, but so what? What should we do with God's love? Give it away! Since God so loved us, we also ought to love one another (1 John 4:11). In other words, our response to the news of God's love for us needs to be to love others. Indeed, Jesus repeatedly commanded us to love others (See Matthew 5:43-47, Mark 12:28-31, Luke 6:27-35, John 13:34-35, John 15:12,17). However, it is impossible to love others unless you know, believe and receive God's love. 1 John 4:19 says, We love because he first loved us. In other words, we are able to love other people, because God first showed His love to us. If God hadn't shown His love to us, we would have no standard and no example on which to base our love for others. Similarly, 1 John 4:7 says, Dear friends, let us love one another, for love comes from God. Here again, our ability to love one another is only because love comes from God. Think of your ability to love others like a glass of water. At first, the glass is empty. If you don't have any water in your glass, then you obviously can't give water to anyone else. But when you hold your glass under a faucet and let the water pour out into your glass, it will fill up. Then, once it is full, your glass will overflow, and you can let the water pour out to everyone around you. If you don't have love in you, then you can't give love to anyone else. Therefore, you must first receive God's love, before you can love one another.

Wisdom is to do now what you will be satisfied with later.

From a practical standpoint, wisdom is to do now what you will be satisfied with later. This means that if you know doing something will be very beneficial later, then you do it now even if you don't want to. The opposite is also true: a person who lacks wisdom will base his or her actions on what feels good right now instead of looking at the long-term picture.

For example, say you want to eat a snack, but you aren't hungry. You might say to yourself, "Well I know I shouldn't eat this, but ... ." And then you decide to keep eating even though you are full. Your actions followed your feelings instead of wisdom, and it's a decision that may lead to results you're not happy with later.

Clearly, wisdom requires using self-control to choose to do what is better. A wise person looks at the end results instead of focusing only on his or her immediate circumstances. In short, wisdom is to do now what you will be satisfied with later.
