There are 3 purposes of laying on of hands:
To ask God’s blessings upon them. Meaning the blessings of God’s protection, guidance, and provision. It is also that they would bring honor to God’s name, and that they would become a mighty and great nation.
‘And He took them up in His arms, laid His hands on them, and blessed them.’ Mark 10:16
To set them apart for God’s service.
They are chosen, full of faith and the Holy Spirit. We pray and lay hands on them as a picture or type of them being set apart and used by god to increase God’s Kingdom.
‘So you shall bring the Levites before the Lord , and the children of Israel shall lay their hands on the Levites; ‘ Numbers 8:10
‘And the saying pleased the whole multitude. And they chose Stephen, a man full of faith and the Holy Spirit, and Philip, Prochorus, Nicanor, Timon, Parmenas, and Nicolas, a proselyte from Antioch, whom they set before the apostles; and when they had prayed, they laid hands on them. Then the word of God spread, and the number of the disciples multiplied greatly in Jerusalem, and a great many of the priests were obedient to the faith.’ Acts 6:5-7
To stir up our God given gift.
Rekindle the blaze God has given us. God has not given us a spirit of fear, but POWER, LOVE, and a SOUND MIND.
‘Therefore I remind you to stir up the gift of God which is in you through the laying on of my hands. For God has not given us a spirit of fear, but of power and of love and of a sound mind.’ 2 Timothy 1:6-7
