"And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. If ye shall ask anything in my name, I will do it." (Jn. 14:13-14)
"Praying always with all prayer and supplication in the Spirit..." (Eph. 6:18)
The Bible teaches us to pray to the Father, in the name of the Son, and in the power of the Holy Spirit. God is interested in communion with us. Prayer is an excellent way to put into practice our belief of the Trinity.
