What does it mean to testify to love?

from the old testament

• Love is foundational to who God is and how He relates to His people. God reveals Himself as “abounding in steadfast love and faithfulness” (Exodus 34:6). To testify to love begins with recognizing that true love originates in God’s character, not in human feelings or preferences.
• The Hebrew word often used for God’s love, hesed, refers to steadfast, covenant love—love that remains faithful even when it is costly (Exodus 34:6–7; Psalm 136). God demonstrated this by rescuing Israel from Egypt (Exodus 15:13), providing for them in the wilderness (Deuteronomy 8:2–4), and remaining faithful despite their repeated rebellion (Nehemiah 9:16–19; Hosea 11:1–4).
  
• Love is not merely emotional affection but a life oriented around worship, trust, and obedience to God. Deuteronomy 6:5 commands God’s people to love Him with all their heart, soul, and strength.
• The heart is deceitful above all things and desperately wicked (Jeremiah 17:9). This warns us that sometimes what we love is not good and that we can easily deceive ourselves into thinking that what we want is love when really it is lust.
• Love for God must fuel love for others. Leviticus 19:18 commands, “You shall love your neighbor as yourself.” Israel was also commanded to care for the poor, widow, orphan, and foreigner through mercy, justice, compassion, and sacrificial care.
• To testify to love is to reflect God’s character before the world. Israel was meant to display what God was like among the nations (Deuteronomy 4:6–8; Isaiah 49:6). When they acted with justice, mercy, faithfulness, and compassion (Micah 6:8; Zechariah 7:9–10), they testified to the reality of the God who loved them first (Deuteronomy 7:7–8).
  

from the new testament

• The New Testament declares, “God is love” (1 John 4:8). God, who is holy and perfect, just and righteous, faithful, good, true, merciful, gracious, patient, sovereign, wise, eternal, and more is the definition of love. To testify to love means living in a way that reflects God and what love is.
  
• Love is a self-sacrificial commitment to seek the good of another person in a way that reflects God’s character. It encompasses all of who God is: holiness, truth, humility, patience, forgiveness, truth, compassion, service, and more (1 Corinthians 13:4–7). If something is not good, true, and holy, it is not love. If it is not selfless, merciful, or kind, it is not love.
• God testified to His love by sending Jesus to save sinners through His death and resurrection (Romans 5:8; John 3:16). Biblical love is sacrificial, for the good of others.
• Jesus defined love as being self-sacrificing. Jesus said, “Greater love has no one than this, that someone lay down his life for his friends” (John 15:13). Love is willingly giving oneself for the good of others.
• Love is not defined by our feelings, desires, preferences, or personal wants but by who God is and how He has revealed love through Jesus Christ and His Word (1 John 4:8–10; John 13:34–35).
• Jesus taught that the world would recognize His disciples by their love for one another (John 13:34–35). Christians testify to God’s love when they forgive, serve, show patience, bear burdens, and pursue unity (Ephesians 4:32; Galatians 5:13; Colossians 3:12–13; Galatians 6:2; John 17:20–23).
  
• Love is inseparable from truth and holiness (Ephesians 4:15; 1 Peter 1:15–16). It is not permissiveness or the affirmation of sin, even though people may argue that love means simply affirming what someone wants or desires. People can desire or “love” what is sinful, but that does not make it true or good (John 8:34).
• True love seeks another person’s ultimate good, which includes pointing them toward repentance, truth, and life in Christ (Ephesians 4:15). 
  
• Galatians 5:22 identifies love as the first fruit of the Spirit. Christians do not merely manufacture biblical love through effort; God transforms His people so they increasingly reflect His loving character. That is because our hearts are deceitful, prone to wander, and idol-factories. We easily love what is not good or true. Only God can transform us to actually love like God does and to love what He does. 
  
• 1 Corinthians 13 describes love as patient, kind, not envious, humble, not proud, does not dishonor, not self-seeking, not easily angered, not keeping a record of wrongs, not delighting in evil but rejoicing in the truth (1 Corinthians 13:5-6). It protects, trusts, hopes, and perseveres (1 Corinthians 13:7). It is enduring and never fails (1 Corinthians 13:8).
• First John teaches that believers should not love “in word or talk but in deed and in truth” (1 John 3:18). To testify to love is therefore to visibly embody God’s character through how one lives and treats others. Love leads to action.

implications for today

Love is love. This is true if you understand what love is. But the world uses “love is love” to redefine love as whatever a person feels, desires, or wants in the moment, making love self-defined rather than God-defined. But love shaped by human preference will always fail.

God, who is eternal and eternally good, faithful, and true, is the only One who will never fail. He is the definition of love itself. And when love is detached from truth and who God is, it becomes indistinguishable from approval of anything, including sin. We very easily deceive ourselves of what we want and what we love. We can easily "want" something so much that we think we love it and convince ourselves that that is love. But, that is lust, not love. How easily we love someone one day and not the next after they have hurt us. How easily we say that we love tacos or a specific sports team in the same sentence as saying we love our spouse. But those loves are not the same.

Only love as defined by the One who is love lasts. That kind of love always seeks the true good of others, even when that requires correction or sacrifice That kind of love always seeks what is truly good, which doesn't change, instead of feelings, desires, fads, and wants, which are all subject to change. Real love is therefore not whatever we declare it to be but what God has shown it to be.

When we testify to love, then, we, as believers, choose to reflect God's love in the way we live and the way we treat others. It means we choose to love what God loves and hate what God hates, knowing that it ultimately leads to destruction. It means being a witness to God's love in a world that confuses love with lust by living out and loving what is real, what is true, and what will never fail.
