OUTLINE:

Your deeds are a reflection of where your heart is.
(Mt 7:15-23, 15:18)

Love’s Expression
If love for Christ is your root system/your motivation, then your deeds will be good/fruitful, bringing glory to God. 2Co 5:14

Dealing With Disappointment
If you find that you're deeds are inadequate, or inappropriate, God wants you to examine your heart, and to turn to Him  and His Word for help with fixing it. Mk 9:24, Lk 17:5 
i.e.- "increase my faith Lord!"

“keeps”
tereo - to keep, guard, observe, watch over (Strong’s Concordance). Is in the present tense, active voice, which means that it is something a person does habitually.

“has been perfected”
teleioo - (Strong’s): (a) as a course, a race, or the like: I complete, finish (b) as of time or prediction: I accomplish, (c) I make perfect; pass: I am perfected.

MacDonald On 1Jn 2:5
The ‘love of God’ does not refer to our love for God, but rather to His love for us. The thought is that God’s love toward us has been brought to its goal when we keep His word. It accomplishes its aim and reaches its end in producing obedience to Him.

Sanctification
God sanctifies our hearts. Fruit is the evidence of His love abiding in us. Increasing evidence means increased sanctification (e.g. we “keep His word” - 1Jn 2:4-5).

Sanctification
If truth ever puts us back into bondage, it’s not truth’s fault, it’s our own. Truth sets us free, by God’s design.

Premeditation
This is the root sustenance of an evil lifestyle. Such a lifestyle would immediately halt if we quit planning and “feeding” it. If we know this and refuse to adjust, we are willfully sinning (Jas 4:17).

The Whopper
A lifestyle may not be sinful by itself. However, if you ARE weak in a certain area and you architect a lifestyle that consistently places you in the crosshairs of temptation (and failure), then you are sinning.

Conditional Blessings
The fact that the Bible never skirts the issue of cause-effect when it comes to conditional blessings is something we must take the time to understand wholly.

Our Joy Is Conditional
Joy in time for a believer is conditioned upon obedience (Jn 15:7-11; 16:24).

Lifestyle Vs. Sin
Too many people try to justify their ungodly lifestyles by focusing on a benign lifestyle instead of the consistent sin it produces. If you choose to live an evil lifestyle, it is your choice that stands out as the sin, not necessarily the lifestyle (for it may be fine for someone else).
