Jesus said abide in me, i discovered that the life of Christ inside us is that branch he talks about and since that branch is his, abiding in him would be natural for the branch, because that's what they do.
Abiding in Jesus is in different forms. First are you connected/set free? Second, take time to be alone with God and third do it every moment.
In order to be like Jesus we must abide in him. His life must be active in ours.
