You receive the promise in full.
You need the strength of endurance to reveal the poetry of God’s will, and then you receive the promise in full. For soon and very soon, “The One who is appearing will come without delay!” Hebrews 10:36-37(TPT)

When last did someone promise you something special?

Did you have to do something first.?
How do you feel when you do the task?
Maybe you do not want to do the task.
Perhaps you wish the task were complete and you can receive the reward.
Did you wish you could get the reward without having to do the task?

What is God asking you to do, and you are hesitating?

God will reward you with eternal life.
Furthermore, you will receive an abundance of life while on earth.
“But first, be concerned about his kingdom and what has his approval. Then all these things will be provided for you.” Matthew 6:33(GW)

Are you prepared to do what is expected of you?
Application to Christian life: Serve God diligently. Be patient. Trust God.
HE is faithful to deliver what HE has promised.
