12 The righteous will flourish like the palm tree; It will grow like cedar in Lebanon. 13 Planted in the house of Jehovah, in the courts of our God they will flourish. 14 Even in old age they will bear fruit; they will be vigorous and green, 15 to announce that Jehovah my strength is right, and that in Him there is no injustice.

Notice that verse 15 says that in God it is right and in him there is no injustice.

God's justice corresponds to his justice. Justice is the correct behavior that is associated with what is established in a relationship. God's relationship with men is established through his Law or Word. In his Word, God conditions man's relationship with obedience to the divine will. Every man who works in justice with what God establishes in his Word, God considers him a just or just man.

When man acts in obedience to what God has established, God's response is justice. That is, God shows himself in justice with what he promises in his Word. God does not lie, his throne is established in justice and in truth. When God promised Abraham that he would give the land of Canaan to all his descendants, Abraham first renounced all his comforts to obey God's voice. Abraham, according to his obedience, God showed himself in justice, now, it was up to God to fulfill with Abraham what he had promised. God, over the years, presented Joshua to the people of Israel in the promised land. God also did his part with Abraham when he introduced the people of Israel into the land of Canaan.

God is just and loves justice, when we fulfill God, God also fulfills us.
The righteous person is on the path of justice and obedience. It will always flourish and prosper because God will prosper the righteous in all their ways. The righteous flourish materially, emotionally and spiritually. God makes it bloom like the palm tree, and even in the moments when the palm tree can bend, God with its power will sustain and sustain it.

God will ensure that the righteous remain planted in his temple and in his courts. God takes care of the righteous, will not give his feet to the slide. In old age, God will make it fruitful, just as he did with Abraham when he was 100 years old, which made him procreate the son of promise, Isaac.

Surely we can announce that God my strength is right and in him there is no injustice.
