1Jo.5:4: Victory is in Jesus - The Supreme Relationship in Your 
Life. 

1 John 5:4 (TLB)  Every child of God can obey him, defeating sin 
and evil pleasure by trusting Christ to help him. 

To overcome the world is to gain victory over its sinful pattern 
of life, which is another way of describing obedience to God (v. 
3). Such obedience is not impossible for the believer because he has 
been born again and the Holy Spirit dwells within him and gives him 
strength. John speaks of two aspects of victory: (1) the initial victory 
of turning in faith from the world to God ("has overcome"); (2) the 
continuing day-by-day victory of Christian living ("overcomes"). [NIV SB] 

Let no one think he can overcome without the help of God. You 
must have the energy, the strength, the power, of an inner life 
developed within you. You will then bear fruit unto godliness, and will 
have an intense loathing of vice. You need to constantly strive to 
work away from earthliness, from cheap conversation, from everything 
sensual, and aim for nobility of soul and a pure and unspotted character. 
MM144 

Faith is the cause of victory, the means, the instrument, the 
spiritual armour by which we overcome. In and by faith we cleave to 
Christ, in contempt of, and in opposition to the world. Faith sanctifies 
the heart, and purifies it from those sensual lusts by which the 
world obtains sway and dominion over souls. It has the indwelling 
Spirit of grace, which is greater than he who dwells in the world. The 
real Christian overcomes the world by faith; he sees, in and by the 
life and conduct of the Lord Jesus on earth, that this world is to be 
renounced and overcome. He cannot be satisfied with this world, but looks 
beyond it, and is still tending, striving, and pressing toward heaven. 
We must all, after Christ's example, overcome the world, or it will 
overcome us to our ruin. [Matthew Henry commentary] 

Jesus never promised that obeying him would be easy. But the 
hard work and self-discipline of serving Christ is no burden to those 
who love him. And if our load starts to feel heavy, we can always 
trust Christ to help us bear it (see Matthew 11:28-30).  [Life
