If you walk into a gym, lift a few weights and run a little bit, you cannot expect to walk out ripped. Whether you are trying to bulk up, tone, or build strength, it will take months of hard training and consistency.
Galations 6:9-10 states - "Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up. Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers."
Stay strong in the Lord, lean on Him, and put your total trust in Him. Life is hard, and the spiritual battles we face are much harder. But like someone who is trying to get results in the gym, we cannot give up either. We have to keep pushing regardless of if we are tired. If we are consistently serving the Lord we will reap results.
