The image on it tells where it belongs
Luke 20:20 – 26
(Short Message)
The same event is also written in Matthew 22:15 – 22 and Mark 12:13 – 17.
Differently to Matthew and Mark, Luke expressed them as “spies” (20, 21).
Sending spies to the ministry of God is clearly wrong and a serious misconduct that will also bring God’s judgement.
To hide their evil, they disguised to be sincere (20). It is a great sin to lie to God (Acts 5:4 - 5)
Jesus knew their duplicity (23). Jesus is the Word of God (John 1:14, Revelation 19:13).
Regarding to the Word of God, Hebrews 4:12 says
12 For the Word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.
Nothing in all creation is hidden from God’s sight. Everything is uncovered and laid bare before the eyes of Him to whom we must give account (Hebrews 4:13).
Their question on tax was a trap (20 – 22). But Jesus astonished them by His answer (24 - 26).
Jesus didn't say "Pay tax", which expression would make Israelites disagree or upset. Instead, based on the image of Caesar in the coin, money belonged to Ceasar, so Jesus asked them to give back what was Ceasar's. No one could disagree or upset.
After this, Jesus added, "and to God what is God's."
Genesis 1:27 says
27 So God created mankind in his own image,
in the image of God he created them;
male and female he created them.
Mankind have the image of God, therefore mankind belong to God and have obligation to God.
Then, what is our obligation to God?
Ecclesiastes 12:13b says
Fear God and keep his commandments,
for this is the duty of all mankind.
Finally, let us read Ecclesiastes 12:1a together.
“Remember your Creator in the days of your youth”
Summary
A coin has the image of governor on it and we know the coin belongs to the government.
Likewise, we have the image of God in us, and we know we belong to God.
