Paul tells us in Galatians 5:16 that we should “walk in the Spirit”. Just a few verses later he speaks of the fruit of the Spirit which includes love, joy and peace among 6 other attributes.
To “walk in the Spirit” is to bear these spiritual fruits in our lives. Notice this is the fruit of the Spirit, not the fruit of good intentions, our best efforts or our own will power.
Romans 5:5 says that the love of God has been poured out in our hearts by the Holy Spirit. So if we are going to bear fruit, we must first recognize the root from which the fruit comes. If you are a Christian, God has poured His love into you. To bear fruit for Him is to simply let that same love, His love, flow through you. Be a fruit bearer. Let His love and His light flow through you. As you give unto others God will give back into you!
