I believe this comes from an incomplete understanding of what the gospel truly is. Many are taught to "get people saved", but Scripture teaches they are to confess Him as Lord and thus shall be saved. I do believe there ARE saved people who do not follow the Lord completely, we are all in process of discovering His kindness in our life. Scripture is rife with examples of people who were saved, but needed correction. I believe we can sin, but God removes the enjoyment of it. And usually believers sin because they don't quite understand the truth that sets them free. So we need discipleship, honoring one another, encouraging one another, and the Spirit of God to convict us of our righteousness in Him.
Amen! The Spirit of God is within us, and it will ALWAYS lead to correction and discipline. IF you don't have any, then you might think twice about your relationship with our Father in Heaven. You cannot be saved and live like the devil. The Spirit doesn't allow for this, as He is now indwelling in us. EVERYONE that received Christ in the Word of God.... CHANGED! Change is the characteristic of a child of God. Without change, there probably wasn't true repentance.
With this said though, some changes might take awhile. We don't just become perfect and stop everything immediately. Although this can happen to some, the majority it does not. Change takes time, but the fact is that you do change. I was an alcoholic for 20 years and I LOVED drinking. I couldn't wait to get home to drink myself into oblivion once again, by drinking half gallons of whiskey a night. Yeah, it's possible, and I did it. My liver should be so shriveled, I would be dead, but God is merciful. I did not stop immediately after my salvation with my Lord, but my heart did. I did NOT WANT to drink anymore and continually prayed to have it taken from me. But my flesh was weak, and I ran back to it every night still. But my heart, each morning, would repent and cry. I wept! I did not want it anymore. I knew something was different in me, because I didn't want to drink anymore, whereas, before, I loved it.
God did deliver me from drinking... Cold turkey... No 10 step program, no outside influence, other than God, and no help; no withdrawals. One day I woke up and never drank again, and that's been 15 years ago. God is so good to me and I love Him so much, and thank Him DAILY for what He has done for me. Only a powerful, mighty, loving God could have delivered me, and He did.
So yeah, there will be change as a child of God. But we need to always consider that we don't know what people are doing behind closed doors. They may not look like a Christian, as I"m sure David didn't act like one much when he did what he did with Uriah and Bathsheba. I'm sure if we'd a been there watching, we'd a said he can't be saved
So we don't know what they do when they go home. They might be on their knees before God praying for deliverance and praising His name for it. I for one never question someone's salvation, as it's not my job. My job is to share the Gospel and be the light of the world. God judges those without the body of Christ. Ultimately, they are already judged by God. They don't need some high and mighty holier than though holy roller telling them how bad they are and they're going to hell in a hand basket. They need JESUS. Once they get Him, trust me... HE will do the rest. Praise God.
And u're right discipleship is lacking HORRIBLY in our world today. It's a shame
God bless you!
