"So then, since we have a great High Priest who has entered heaven, Jesus the Son of God, let us hold firmly to what we believe. This High Priest of ours understands our weaknesses, for he faced all of the same testings we do, yet he did not sin. So let us come boldly to the throne of our gracious God. There we will receive his mercy, and we will find grace to help us when we need it most." (Hebrews 4:14-16 NLT)
"Of old hast thou laid the foundation of the earth: and the heavens are the work of thy hands. They shall perish, but thou shalt endure: yea, all of them shall wax old like a garment; as a vesture shalt thou change them, and they shall be changed. But thou art the same, and thy years have no end. The children of thy servants shall continue, and their seed shall be established before thee." (PSALM 102:25-28 KJV)
One of the early things I learned, (the hard way,) is that sinning is a slippery slope! You step out and do something you know you shouldn't do, and you will find yourself slipping more and more; the more you sin, the easier it is to feel as though you got away with it.
Unfortunately, you don't get away with anything! We that have been forgiven, we sometimes think it is like having a hall pass; everyone else has to stay in the classroom, being taught, while we get to walk the halls doing whatever we want. It really doesn't work that way, no matter how strong you think you are, the more you skip class, the less you learn to do what is right.
Besides that, the Holy Spirit is a gentleman, He will not force you stay in line! But, sad to say, the less you obey Him, the less He you hear Him speak! We need to stop being free-willed, as if we have the ability to get away with things and think that all will be forgiven. We are only losing out on some great spiritual blessings!
There is a book I shared about several times, called, "Sit, Walk, Stand." There has to be a point in our lives when we realize that we don't walk on our own! If we do not abide in Christ, we will not walk in the Light; if we do not walk in the Light, will surely will not Stand; stand meaning, be victorious...
"Now if we be dead with Christ, we believe that we shall also live with him: knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him. For in that he died, he died unto sin once: but in that he liveth, he liveth unto God. Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Christ our Lord. Let not sin therefore reign in your mortal body, that you should obey it in the lusts thereof. Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God. For sin shall not have dominion over you: for ye are not under the law, but under grace." (Romans 6:8-14 KJV)
