Cool connection I saw in this verse.
Joh 21:18 Verily, verily, I say unto thee, When thou wast young, thou girdedst thyself, and walkedst whither thou wouldest:
but
when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not.

Gal 4:2 but is under tutors and stewards till the time appointed of the father,
Gal 4:3 so also we, when we were babes, under the elements of the world were in servitude,
Gal 4:5 that those under law he may redeem, that the adoption of sons we may receive;
Gal 3:26 for ye are all sons of God through the faith in Christ Jesus,
Gal 4:6 and because ye are sons, God did send forth the spirit of His Son into your hearts, crying, `Abba, Father!'
1Co 13:11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.
1Co 13:10 But when that which is perfect is come, then that which is in part shall be done away.
Rom 8:14 for as many as are led by the Spirit of God, these are the sons of God;
May the Holy Spirit of God continue to move us onto perfection.
