James 1:12

Blessed is the man who perseveres under trial, because when he has stood the test, he will receive the crown of life that God has promised to those who love him.

Blessed is the man who perseveres under trial
James 1:2-3 Consider it pure joy, my brothers, whenever you face trials of many kinds, because you know that the testing of your faith develops perseverance.
Genesis 22:1-2 Some time later God tested Abraham. He said to him, "Abraham!" "Here I am," he replied. Then God said, "Take your son, your only son, Isaac, whom you love, and go to the region of Moriah. Sacrifice him there as a burnt offering on one of the mountains I will tell you about." (read on in Genesis 22 to find out what happened)
James 5:11 As you know, we consider blessed those who have persevered. You have heard of Job's perseverance and have seen what the Lord finally brought about. The Lord is full of compassion and mercy.
1 Peter 3:14 But even if you should suffer for what is right, you are blessed. "Do not fear what they fear; do not be frightened."

he will receive the crown of life
1 Corinthians 9:25 Everyone who competes in the games goes into strict training. They do it to get a crown that will not last; but we do it to get a crown that will last forever.

that God has promised to those who love him
Exodus 20:6 "... but showing love to a thousand generations of those who love me and keep my commandments."
1 Corinthians 2:9-10 However, as it is written: "No eye has seen, no ear has heard, no mind has conceived what God has prepared for those who love him"--but God has revealed it to us by his Spirit. The Spirit searches all things, even the deep things of God.
1 Corinthians 8:3 But the man who loves God is known by God.
James 2:5 Listen, my dear brothers: Has not God chosen those who are poor in the eyes of the world to be rich in faith and to inherit the kingdom he promised to those who love him?
