An obstacle is something that obstructs or hinders progress. Anything contrary to God's Word is an obstacle. Fears, addictions, persecution, and worries can become obstacles as they poison your thoughts. God is always with us and says "His Grace is sufficient, and that His power is made perfect in weakness..... (2 Corinthians 12:9).
Stay focused on God's Word. Believe His promises. "The thief cometh not, but that he may steal, and kill, and destroy [That is, steal your life, joy, and purpose, kill your spirit and soul, and destroy your relationship with God]: I (Jesus) came that they may have life, and may have [it] abundantly (John 10:10). The Scriptures tells us to avoid arguing about nothing to do with nothing because it serves no purpose. "Don’t have anything to do with foolish and stupid arguments, because you know they produce quarrels. And the Lord’s servant must not be quarrelsome but must be kind to everyone, able to teach, not resentful (2 Timothy 2:23-24). Jesus knows what's best. He said, "I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world (John 16:33). God is in control!
Stay Focused on and Yoked to Jesus!
