What will be my core message to those I am discipling and teaching on how to follow Jesus. It will simply be that following Jesus is the best life possible.
On the last day of the feast, the great day, Jesus stood up and cried out, “If anyone thirsts, let him come to me and drink. Whoever believes in me, as[f] the Scripture has said, ‘Out of his heart will flow rivers of living water.’” – John 7:37-38 ESV
Martin Luther had some great thoughts on this when he commented on Psalm 126:2.
Then our mouth was filled with laughter,
and our tongue with shouts of joy;
then they said among the nations,
“The Lord has done great things for them.” – Psalm 126:2 ESV
Then our mouth was filled with laughter, etc. We must earnestly endeavour to learn this practice, or at the least to attain to some knowledge thereof; and we must raise up ourselves with this consideration—that the gospel is nothing else but laughter and joy. This joy properly pertaineth to captives, that is, to those that feel the captivity of sin and death; to the fleshy and tender hearts, terrified with the feeling of the wrath and judgment of God. These are the disciples in whose hearts should be planted laughter and joy, and that by the authority of the Holy Ghost, which this verse setteth forth. This people was in Zion, and, after the outward show of the kingdom and priesthood, did mightily flourish; but if a man consider them according to the spirit, he shall see them to be in miserable captivity, and that their tongue is full of heaviness and mourning, because their heart is terrified with the sense of sin and death. This is Moses’ tongue or Moses’ mouth, full of wormwood and of the bitterness of death; wherewith he designs to kill none but those which are too lively and full of security. But they who feel their captivity shall have their mouths filled with laughter and joy: that is, redemption and deliverance from sin and death shall be preached unto them. This is the sense and meaning of the Holy Ghost, that the mouth of such shall be filled with laughter, that is, their mouth shall show forth nothing else but great gladness through the inestimable consolations of the gospel, with voices of triumph and victory by Christ, overcoming Satan, destroying death, and taking away sins. This was first spoken unto the Jews; for this laughter was first offered to that people, then having the promises. Now he turneth to the Gentiles, whom he calleth to the partaking of this laughter.—Martin Luther.
