We worry ourselves sick about what might happen tomorrow. The Bible says we are not to be anxious about what might happen tomorrow. In other words, God's grace will be sufficient to meet the challenges of each new day. Instead of being a burden to others, you can be a blessing. As you realize God's power, comfort and strength through life's experiences, you will grow in your faith.
Temptation is a part of life.
It was before you received Christ, and it still will be. It is not a sin to have wrong thoughts from time to time. It is, however, a sin to choose to dwell on such thoughts over and over again. When Jesus was tempted in the wilderness, He replied to the devil by quoting Scripture. Be prepared for temptation, through prayer and through your knowledge of God's Word.
