He who has the Son has life. There seems to be a type of Symbiotic relation between the believer and Christ. We are in Him and He is in us. He keeps us in eternal life, so long as we remain in Him.
James 1:12 Blessed is the man that endureth temptation: for when he is tried, he shall receive the crown of life, which the Lord hath promised to them that love him. (KJV)
Jesus further gives us a glimpse into this relationship in Matthew 24:13 But he that shall endure unto the end, the same shall be saved. (KJV)
Jesus obviously both provides for and sustains those who trust in or abide in Him. But it is obvious that those who do not endure through the trial will not receive the crown of Life.
John 15:1 I am the true vine, and my Father is the husbandman. 2 Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit. 3 Now ye are clean through the word which I have spoken unto you. 4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me. 5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. (KJV)
Trials come into every believers life and they define who we are in Him. I have stated before in these blogs that our belief is the determining factor with God, who looks upon the heart, and knows our beliefs. Why are beliefs important, because we act on our beliefs. Just look at the accounts in the gospels of the religious men in Israel, whom Jesus condemned. They did not believe in Him even though they were in possession of the scriptures that pointed to Him. Fortunately some believed.
Abraham believed God and it was accounted unto him as righteousness.
Abraham very probably did some serious weeping and talking with God, before he took Isaac up to be sacrificed.
Blessed are those who weep now for you shall laugh (Luke 6:21)
Take care, brethren, that there not be in any one of you an evil, unbelieving heart that falls away from the living God. For we have become partakers of Christ, if we hold fast the beginning of our assurance firm until the end, And to whom did He swear that they would not enter His rest, but to those who were disobedient? So we see that they were not able to enter because of unbelief.
Hebrews 3:12,14,18-19 NASB
You have been severed from Christ, you who are seeking to be justified by law; you have fallen from grace. For we through the Spirit, by faith, are waiting for the hope of righteousness. You were running well; who hindered you from obeying the truth? This persuasion did not come from Him who calls you.
Galatians 5:4-5,7-8 NASB
It is easily seen in these verses that there are testings that come which will try our faith — what we believe.
John 15:6 If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned. (KJV)
It is also obvious from these verses that we have a personal responsibility to God to follow His word.
Paul in Galatians asks the question — who has hindered you…? The answer to that question is also obvious from these verses. We are the only ones who can lose or give away that gift that has been given to us. Jesus promised to let no man take it from us, but He obviously did not include our own personal responsibility to Him in this promise.
