Supplication

Historical, non-Christian supplication is most likely addressed by Jesus in the following passage:

But when you pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking. - Mat 6:7

God is the most intelligent being in the unverse. He hears us the first time we speak. As a matter of fact, He knows what we need before we even ask. On top of that, He knows the imagination of the thoughts of our Hearts.

Prayer? Keep it simple. Keep it sincere.

Be not you therefore like unto them: for your Father knows what things you have need of, before you ask him. - Mat 6:8
In Prayer 'acknowledgement' should be a mainstay. acknowledge His sovereignty. acknowledge His goodness. acknowledge His blessings. acknowledge His Love. acknowledge His provision. acknowledge His Plan.

Unfortunately, despite Jesus' teaching on heathen supplication, Christians have been taught that it works.
Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints; - Eph 6:18
Talking to God in the Spirit ( Prayer Language) is how we build ourselves up in faith (Jud 1:20).      Praying for one another produces unity and strength in the body.
When we have asked and believed that we have received the request, we then persevere until we see the manifestation (Mar 11:24).

When we supplicate as is indicated in the above verse, we are earnestly asking God to bless another individual. It does not mean that we should use repetitive language with emotionally charged begging. Such behaviour is evidence of a lack of trust in God's Word and His love for us. In other words it is evidence of unbelief.
