Once we are His we are His. He will hold us and keep us. We may falter and fail and stumble and fall, but He will keep us from falling out from Him. We see in 1 Peter 1:5 “You, who by God’s power are guarded through faith for a salvation ready to be revealed in the last time” We also see Paul saying, “I know whom I have believed, and I am convinced that he is able to guard until that day what has been entrusted to me” (2 Tim. 1:12; see also John 10:28).
When one believes they receive everlasting life right then. It is a present possession for the one who believes. “Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life” (John 5:24). This is but one of many Scriptures throughout the gospel of John that shows we are in present possession of everlasting life when we believe. We have passed from death to life. Life is ours in Christ.
The verse above from John 10:28 states that Jesus gives eternal life and the one who has this will never perish or be snatched from His hand. This is true because He and the Father are one and God the Father is greater than all. Since God “is not a man, that He should lie, Nor a son of man, that He should repent. Has He said, and will He not do? Or has He spoken, and will He not make Good?” (Num. 23:19; c.f., 1 Sam. 15:29; Titus 1:2; Heb. 6:18).
Since God cannot lie, and will not lie, and we are told that nothing can snatch us out of His hand, then this means nothing. We are a something so this even places us in this category. We cannot sin large enough to be removed nor can our unbelief remove us. If you have believed in Jesus Christ and received everlasting life it is yours even if you get to a point later where you do not believe anymore. You are in His hand and nothing can snatch you out.
This is why Paul could write, “For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord” (Rom. 8:38-39). The love of the Lord is found in John 3:16. He died so we can live. Nothing can separate us from that if we have believed in Christ.
We are sealed by the Spirit (Eph. 1:13). This sealing is unto the day of redemption (Eph. 4:30). We are new in Christ (2 Cor. 5:17). We are born again (John 3). We are a part of the body (Rom. 12:4-8; 1 Cor. 12:12-31). We are His and that means He keeps us.
We cannot fall away and not be His anymore. No, that cannot happen. But we can fall back into worldly ways. We can fall into sin and waller in it. But, if we let Christ have his way with us, and if we seek to know Him and follow Him and imitate Him, we will not fall. We will be conformed to His image and act as we should. We will walk in His ways and have deep intimate fellowship with Him.
God has a plan and a desire for us, and that is for us to be faithful and leaning on Him always. We are not meant to fight alone. No one ever fights alone. The boxer has a cornerman. The tennis player has coaches and helpers. No one fights alone. Even as great as those are those are for the athlete, they are nothing compared to Jesus Christ in your corner. If you are His, then He is in your corner. He is there and able to keep you upright, just let Him, let Him have His way with you.
