John 16:24

The disciples had not appealed to the Father in Jesus’ name before now. As Old Testament believers, they had undoubtedly grounded their petitions on God’s promises in the Old Testament. However the entrance that Jesus now gave them with the Father would assure an even warmer response to their prayers than Old Testament saints received.

Jesus urged His disciples again to ask the Father. The verb in the Greek text is a present imperative (aiteite, from aiteo). He also gave them assurance that they would receive what they requested "in His name" (cf. 1 John 5:14-15). The consequence of answered prayer would be fullness of joy for them (cf. John 15:11; John 16:22).

Jesus brought many of the themes of chapter 15 together in this concluding promise: loving obedience, asking, receiving, joy, and fruit-bearing.
