Summary: Wee need to seek and follow and pursue after God with a passion comparable to the way He seeks us out!
A Psalm of David, when he was in the wilderness of Judah.
O God, thou art my God; early will I seek thee: my soul thirsteth for thee, my flesh longeth for thee in a dry and thirsty land, where no water is; To see thy power and thy glory, so as I have seen thee in the sanctuary. Because thy lovingkindness is better than life, my lips shall praise thee. Thus will I bless thee while I live: I will lift up my hands in thy name. My soul shall be satisfied as with marrow and fatness; and my mouth shall praise thee with joyful lips: When I remember thee upon my bed, and meditate on thee in the night watches. Because thou hast been my help, therefore in the shadow of thy wings will I rejoice. My soul followeth hard after thee: thy right hand upholdeth me. But those that seek my soul, to destroy it, shall go into the lower parts of the earth. They shall fall by the sword: they shall be a portion for foxes. But the king shall rejoice in God; every one that sweareth by him shall glory: but the mouth of them that speak lies shall be stopped. Psalms 63:1-11 (quickview)  KJV
1. THE CHURCH HAS BEEN COMMISSIONED TO BE WITNESSES UNTO HIM.
And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen. Matthew 28:18-20 (quickview)  KJV
And he said unto them, Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned. And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover. So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God. And they went forth, and preached every where, the Lord working with them, and confirming the word with signs following. Amen. Mark 16:15-20 (quickview)  KJV
Then opened he their understanding, that they might understand the scriptures, And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. And ye are witnesses of these things. And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high. Luke 24:45-49 (quickview)  KJV
But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. Acts 1:8 (quickview)  KJV
