pray: boldly or humbly?

there's something about... prayer
to pray to God, should one be soft and humble and .. contrite?
or should one speak boldly with charisma and power?

is it a stance that we come before God knowing that He is so much greater and we small?
or because of what Jesus has done on the cross, we can come before the Father confidently?

i grew up with the latter train or taught, and only when i reached university i see a different form of praying to God. i guess it really does depend on the situation that we are in at the moement and how the Holy Spirit uses us.

Matthew 10:19&20: "But when they hand you over, do not worry about how to respond or what to say. In that hour you will be given what to say. For it will not be you speaking, but the Spirit of your Father speaking through you"

so yeah, this verse always come to my mind when i'm about to pray.
its not about what i know as a human, but how available i am as a vessel for God to use right?

also another big contradiction
there's something about.... ministries.
i see that CLC is very strong in evangelism and a very go-out and get em method.
and CL is more of focus on the ones whom come into the fold method

both reaches out to non-believers (or pre-beleivers as some prefer the term) but in a different way.
its so interesting. as if, the wester tries to improve one's own personal self more, and the eastern has its considerations on others. which is deeper which shallow. which is the great commission which is just... a tradition.

never the less, as long as Christ is preached. we all have our different ways to serve the same body.
