Jeremiah 29:12-13

Then you will call on Me and you will come and pray to Me, and I will hear (your voice) and I will listen to you. Then (with deep longing) you will seek Me and require Me (as a vital necessity) and (you will) find Me when you search for Me with all your heart. 

We pray and seek God because He is vital to the believer’s life. God wants to fellowship with us and have a relationship with His people. When we incorporate God into our lives, He will lead and guide us with the Holy Spirit. We are to call upon God and let Him hear your voice in prayer!
