A very powerful way to love others is to pray for them. If we are not praying for others we are not loving them.
James 5:16: Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
Notice how often the words thy, thine, our, us and we appear in the prayer that Jesus taught. Notice also the absence of the word me. It is not a selfish prayer.
Matthew 6:9: After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name. 10 Thy kingdom come. Thy will be done in earth, as it is in heaven. 11 Give us this day our daily bread. 12 And forgive us our debts, as we forgive our debtors. 13 And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, for ever. Amen.
It is a good thing to be a blessing to others but how much greater is it when God blesses them? It is a gross understatement to say that He is better able to bless them than we are. And, of course, when we pray fervently for others it will often happen that He uses us as instruments of blessing to them. One of the best things we can pray for ourselves is that He will make us a blessing to others. What good is it for us to pray for others if we are not willing to be used of God to bless them to the extent we are able? There is often a direct connection between praying for others and blessing them ourselves. Fervently praying for others is one evidence that we love them.
Luke 10:27: And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.
