https://youtu.be/jCvN2KQjxjo?si=qf7eFKaebcnMjSt5 when we talk about giant we don't mean physical physics, hight, shape or structure or most at times when ever we hear someone call giant what comes to our mind is that the person is too mighty, is too tall, is too huge.
If you are in Christ Jesus you are a giant infact you are too big because you are a child of God your weight alone can't be measured.
You can be small and desame time a giant, when it comes to Christianity a little boy or a girl can be a Giant more than a grown up or adult because we are in Christ Jesus and one with him is with majority so you are a giant by nature.
So we shouldn't be limited to all our little understanding or our little knowledge. We don't determine giants by age.
