Is the power and love of God enduring in you? Is your Christian life having results to it? The word "therefore" is referring to the results, conclusions, or applications that are to be in our lives from the reasons given.
The devil wants to get a hold on us so he can attack to discourage and sway us away from God and His ways. Our defense is simple; we are to stand firm in Christ, pray, and allow His work in us and not ours; what we would bring to the table is just fuel for the devil and his ways!
God is calling us to be proactive with our faith so we can grow and be mature. This requires us to be faithful which requires us to submit and to be humble. The result is respect, cooperation, unity, community, and the power of His Fruit at work.
Most Christians ignorantly will state that the law has nothing to do with then since they are under grace. But, according to the Bible, this is not the case!
God does not reject us; rather, it is us who reject Him, He goes out of His way to give us the grace we do not deserve. He gives us His Way, even though we continue to fight against Him by hardening our hearts and rejecting His Truth and precepts.
The key we need to understand is this, sin entered in the world by one man that affected all people by Adam; but the grace of God, which justified us, comes in the world by one man/God. All of humanity deserved it, Christ did not; thus, yes it is unfair- to God, but not to us!
Being a true disciple means having a willingness to trust Him completely in all aspects of life from the highest highs to the lowest lows. It means we are not only willing to trust Him to provide for our salvation, but also for the future.
The key to the success of finding and developing faith is simple; it is obedience. We must be ready to serve God rather than our needs, even before we know what the call may be, and take this mindset into life and to others.
Our perspective is eternity. It is not to be just on money, wealth or power. When we see our life here on earth as a mere rehearsal, and how to learn and build to what is to come in eternity, we can be better prepared to face anything-even dire situations and death, because our eyes and attitude are in Him and not our circumstances!
God asks us to have an "eternal" perspective! The premise is to move us to more maturity by moving our mindset away from the false beliefs and ideas we have built up. What we tend to pursue, in our desires in life, is meaningless against the backdrop of seeking faith and the call that Christ gives us.
