Practice...it makes perfect: NOT in behavior, but in continual connection with Him. When that happens, when you sit with Him, there is no good or bad, there is just you and Him, abiding and enjoying each other. There, when you aren't even aware and haven't been focusing on it - poof! change happens, growth occurs, and fruit is seen.
Ps 1:3, And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper.
Both the fruit and leaf are mentioned.
It isn't ALL about bearing Christian 'fruit', but additionally about abiding by the river of His living water which keeps us in a state of readiness to bear fruit - in season and out.
Note that the fruit is seasonal, but the leaves are always present. We are always ready to bear fruit, for there is no season of lifelessness in the Christian who abides.
In your abiding you are perfect, whether or not you are "in fruit". Relax. Rest. Trust His seasons.
