Hebrews 10: 26
" For if we go on sinning deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins."
It's always enjoyable to share God's promises & God's love for you & me but it's also necessary to share the hard truths.
God is FULL of grace & love but we can't use that as an excuse to do whatever we want. Sometimes we sin and we are not aware of it at all! For example you might be venting to a friend but you are gossiping without realizing it. Once you are aware of your sin you are given a choice; tell God you are sorry and then change your ways or you can say "I don't care what God thinks" and continue in your sin.
Everyone will sin. You aren't the only one who makes mistakes. When you sin, go to God right away and ask Him for forgiveness. He can redeem you and He can make you new. God knows everything going on in your life so just be open and honest with Him. If you are stuck in a long list of lies right now, go to Him and ask what you should do. He will guide you step by step to freedom.
