The love that we possess as believers in the Lord Jesus Christ is wrought within us by the Holy Spirit, whom Christ purchased for us as a gift by all that He did for His people.
We look at the love which is the fruit of the Spirit; a love which begets faith which in turn gives rise to hope. Then hope strengthens faith and faith enhances our love as we are more and more conformed to the image of Christ.
In consequence, we are exhorted to strive to be filled more and more with the Holy Spirit, making full use of the means that God has provided to that end. Likewise, we should lay aside the sin that will grieve the Holy Spirit and the unbelief that will quench His working in our lives.
