Matthew 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Describing Christianity is quite different than living out the principles and laws of God’s kingdom, for a person may be able to describe or define the many aspects of the Christian’s life, without them actually walking the walk. To give out a lot of information just for information’s sake, does nothing to heal the wounds of the soul, neither do such methods prompt sinners to repent. And worse yet, Christ is hidden from view, under the mirage of intellectual sophistries that wearies souls.
Hence the reason why Jesus found it necessary to personally ordain the twelve, for He would be with them to not only instruct them but to give them the hands-on knowledge they would need, in order to effectively preach Christ and the Gospel.
[The Desiree of Ages pp 296] When Jesus had ended His instruction to the disciples, He gathered the little band close about Him, and kneeling in the midst of them, and laying His hands upon their heads, He offered a prayer dedicating them to His sacred work. Thus, the Lord's disciples were ordained to the gospel ministry.
Acts 1:8 But you shall receive power, after that the Holy Ghost is come upon you: and you shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
May God add His blessing to the study of His word. “Good night” and God bless!
