Reason #12: They have a guilty conscience.
Hebrews 10:22 says, “Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience and our bodies washed with pure water.” Many times, people who doubt their salvation are in a sinful lifestyle, they have a sin issue they have not dealt with, or a sin issue in their past so huge they do not believe God has forgiven them nor could forgive them. Therefore, they are stuck. They need to surrender this area or these areas to the Lordship of Christ. If you find yourself in this dilemma, we should probably talk. People who do not doubt their salvation have a clear conscience. They are walking in victory and the assurance made possible by the Holy Spirit.
God is transforming genuinely saved people into the image of our Lord Jesus. However, we are not there yet. When we “slip off the path” of faithfully following Jesus, we will come under the conviction of the Holy Spirit. We will leave that sinful lifestyle and pursue holiness. If we resist His conviction, we will quench the Spirit. When we quench the Spirit, the Provider of assurance, doubting salvation will follow. If this could be a reason for doubt in your life, utilize 1John 1:9; God’s remedy for dealing with sins and sinful activity after salvation. Let me know if I can help.
