It goes without saying, yet there is a need to say it: love is the primary driver and content of all that we do.
We know that without love our actions have no meaning to God.
Knowing this, now we look to specify the content. There are many frameworks that can help. Choose the one that works for you.
What to do and when to do it: we can spend our time thinking about what we do to express love. What are the specific actions? The second aspect that is important is when the do the action. Timing can be everything.
Anchored feelings to flow through actions: Sometimes what is important is not the content but the way the content was delivered. This does not mean that the content is not important. It simply stresses the character of the content which creates the atmosphere of love.
Walking in the spirit: this is undoubtedly a more spiritual expression which tends to make referencing specific actions more difficult. Nonetheless, the implication of obedience that is closely tied with walking in the spirit is vital for expressing love. It can be connected to the what to do framework in that God is telling you what to do and when to do it. It can be connected to the anchored feelings framework in that walking in the spirit we will not fulfill the lust of the flesh and thus will be feeling something else while we walk.
Where there is no love there is no Spirit of God. For any of our actions to be worthwhile in our pursuit of God and the evangelism of his message, love must be our primary concern. This moves the conversation from whether or not to love to what does love look like.
