There are at least five fruits of abiding in Christ:
Spiritual Fruitfulness
“I am the vine; you are the branches. Whoever abides in me and I in him, he it is that bears much fruit, for apart from me you can do nothing.” – John 15:5
Answered Prayer
“If you abide in me, and my words abide in you, ask whatever you wish, and it will be done for you.” – John 15:7
Peace in the Storm
“I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world.” – John 16:33
New Life
“Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.” – 2 Corinthians 5:17
Robe of Righteousness
“and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith.” – Phil 3:9
