Never Sis! God knows your heart and He does not condemn when we are trying to be obedient. I had to stop a fast before because my heart was not in the right place and I found myself having an attitude. I find that preparing before a fast is best for me. I pick a day or days that I do not have much planned and five days before I start eating less, cutting snacks and sweets. The day before, I eat just one meal and then I go into my fasting. I pray whenever I feel the need to, I watch sermons and I listen to worship. I work so If I do 3 days of fasting I do have to work during the fast but I’ll pray in the morning and night and listen to His word through podcasts or the Bible app. Always remind yourself you are doing this as a sacrifice to grow closer to God and when you get hungry pray for His strength. I always use “And He said to me, “My grace is sufficient for you, for My strength is made perfect in weakness.” Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me.” II Corinthians 12:9 NKJV. God bless you Sis. God loves you!
