I remember reading this verse in middle school or high school and it having a significant impact on me. It made me meditate on what it means to not boast in serving others but rather to do ALL things for the glory of God "who sees in secret" (Matthew 6:4).
This scripture also reminds me of the saying, "No strings attached" which can be compared in contrast to the adage, "I'll scratch your back if you scratch mine."
Christ Jesus' sacrifice, compassion, (and mediation) on my behalf (and for your benefit and for all of mankind) so that I (and everyone else for that matter) can have a relationship with God where sitting at the foot of His throne and communing with Him is permitted, was an act without expectation of something in return. He did not say, "Now what are you going to do for me?" but rather, "It is done."
16"For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. 17For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him." (John 3:16-17. ESV.)
Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God, and afflicted. But he was wounded for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his stripes we are healed. All we like sheep have gone astray; we have turned—every one—to his own way; and the LORD has laid on him the iniquity of us all. (Isaiah 53:4-6. ESV.)
For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast. (Ephesians 2:8-9. ESV.)
And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, 14by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. (Colossians 2:13-14. ESV.)
For while we were still weak, at the right time Christ died for the ungodly. 7For one will scarcely die for a righteous person—though perhaps for a good person one would dare even to die— 8but God shows his love for us in that while we were still sinners, Christ died for us. (Romans 5:6-8. ESV.)
For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God. (2 Corinthians 5:21. ESV.)
Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, 4to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, (1 Peter 1:3-4. ESV.)
In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. 10In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins. (1 John 4:9-10. ESV.)
...because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. 10For with the heart one believes and is justified, and with the mouth one confesses and is saved. (Romans 10:9-10. ESV.)
I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me. (Galatians 2:20. ESV.)
