Some things in life are done by appointment only most of the time...see the doctor, get the oil changed in the car, get a haircut, see a consultant, etc. In this day and age, it's beneficial to make an appointment in order to make the most of one's time. Knowing when one has to be somewhere and approximately how long it will take gives us the opportunity to plan the day and create a schedule, plug in other tasks or errands in convenient ways to save time, energy, and work. Some places schedule only appointments for their business; some do both appointments and allow for walk-ins; some do just walk-ins. People live by a schedule, a daily appointment calendar that tells the things one needs to do. And if an appointment is forgotten it may change the whole day or even the whole week's plans if needing to re-schedule.
Some things in life don't require appointments. A child doesn't come to a parent and say I need to make an appointment with you later today so I can tell you that I love you. A parent doesn't tell his/her child that they have an appointment with them at 1 pm to sit on my lap. Relationships are an ongoing part of one's life and two of the building blocks for a good relationship is spending time with one another and having conversation with each other.
While our current societal circumstances and social distancing guidelines have lessened the "walk-ins welcome" opportunities, there are still those opportunities for growing relationships and for offering expressions of love.
One relationship involving both of those building blocks is prayer. Prayer is spending time with God and is having a conversation with Him. Some say prayer is a "reporting for duty" and as such, it means listening is a part of the conversation as well - to seek to hear His voice, to let Him apply His Word to our lives. Prayer is also an expression of love. While we have our own appointed times that we perhaps have created for prayer such as a regular devotional or study time, prayer when we get up and when we go to bed, and prayer at mealtimes, we know we don't have to call God to make an appointment for prayer time with Him. His door says "walk-ins welcome" and that means 24-7. Prayer as an expression of love is an ongoing or as the Apostle Paul puts it "unceasing" part of life. In 1 Thessalonians 5:16-18 (NRSV), he wrote:
Perhaps there are times when someone we know is going to be in our vicinity. I know I tend to look more to spot someone that I hope or expect to be present. Knowing that God is always in our vicinity, do we think to look more for Him in every place, every thing, every person, every circumstance, every situation...? You may get the idea. God has opened Himself up to us, loving us first, seeking our attention, desiring for us to spend time with Him and hear what He has for us. He has given us the ultimate expression of love through His Son. Our souls are nurtured and nourished when we spend time in His presence. Where will you see Him today? Where will you experience His presence? How is He nourishing your soul this day? May our door to Him and to others He sends our way say "walk-ins welcome." In Jesus' name. Amen
