1 Corinthians 16:13-14 (CJB), "Stay alert, stand firm in the faith, behave like a [man]1, grow strong. Let everything you do be done in love."2
Growing strong, being a man (of integrity, honor), being firm in your faith, staying alert -- these are all good things, but if you do not do it in love, it's all for naught.
1 Corinthians chapter 13 explains it well:
1 Corinthians 13:1-10 (CJB), "I may speak in the tongues of men, even angels; but if I lack love, I have become merely blaring brass or a cymbal clanging. I may have the gift of prophecy, I may fathom all mysteries, know all things, have all faith — enough to move mountains; but if I lack love, I am nothing. I may give away everything that I own, I may even hand over my body to be burned; but if I lack love, I gain nothing. Love is patient and kind, not jealous, not boastful, not proud, rude or selfish, not easily angered, and it keeps no record of wrongs. Love does not gloat over other people’s sins but takes its delight in the truth. Love always bears up, always trusts, always hopes, always endures. Love never ends; but prophecies will pass, tongues will cease, knowledge will pass. For our knowledge is partial, and our prophecy partial; but when the perfect comes, the partial will pass."3
A couple of verses in Ephesians chapter 5 should also be mentioned:
Ephesians 5:1-2 (CJB), "So imitate God, as his dear children; and live a life of love, just as also the Messiah loved us, indeed, on our behalf gave himself up as an offering, as a slaughtered sacrifice to God with a pleasing fragrance."4
Without love, nothing we do is worth doing. Without love, our actions don't count in the hear after. A life without love is a life without Adonai, for G-d is love.
1 John 4:8 (CJB), "Those who do not love, do not know God; because God is love."5
... and ...
1 John 4:16 (CJB), "Also we have come to know and trust the love that God has for us. God is love; and those who remain in this love remain united with God, and God remains united with them."6
So, learn what love is and walk in it daily, as we all work out our salvation7 in Yeshua.
